Definitions
- the invention relates to the field of technical physics, in particular to spectral methods for determining the elemental composition of liquid media using an electric discharge in a liquid as a source of spectra. This method can be used to determine the elemental composition of liquid media.
- the field of application is in water treatment systems at water supply enterprises of settlements, in the nuclear and thermal power industry, in the chemical industry, in the technological process of the food industry for monitoring water quality, in environmental monitoring of environmental objects and in other areas.
- a voltage (1.2 - 2.8) kV is applied to the electrodes of the cell, depending on the composition of the analyzed solution and the channel dimensions.
- the high-voltage electric circuit is closed in the channel, where the current density is much higher than in the rest of the vessel, as a result of ohmic heat release, liquid boils and a vapor bubble forms. Then the channel is blocked by a steam plug and a gas discharge arises between its walls, which is accompanied by the emission of light.
- the radiation intensity of metals in the RVC plume serves as an analytical signal for further recording of emission spectra using a spectrometer.
- the disadvantage of this method is that the recorded intensity of the emission spectra for most elements, including for alkaline earth metals, is small, much lower than for alkali metals (the detection limit, according to the authors, for sodium was 0.05 ppm, for calcium - 1.5 ppm, for magnesium - 5 ppm).
- the closest analogue to the invention is a method of emission analysis of the elemental composition of liquid media based on a local electric discharge (LER) in a liquid [RF patent for invention No. 2368895, G01N 27/62, 09/27/2009.].
- LER local electric discharge
- an electric current is also transmitted through the analyzed liquid by means of electrodes separated by a baffle (membrane) made of a dielectric material with a diaphragm opening made therein.
- LER local electric discharge
- the LER is initialized after polarization of the aforementioned electrode with the current of the same polarity as the LER current.
- the magnitude of the polarization current is less than the magnitude of the current required for the appearance of the electron beam laser, but sufficient to ensure effective mass transfer between this electrode and the ions of the analyzed liquid (in practice, 0.1-0.3 of the laser beam current).
- the emission spectra excited by the LER are recorded with the aid of a spectrometer.
- the disadvantages of this method are the presence in the recorded spectrum of the analyzed liquid of the emission lines of the electrode material and the spatial instability of the radiation recorded by the spectrometer due to the displacement of the discharge over the electrode surface. Both disadvantages are due to the location of the electrode in the discharge region, which leads to its gradual destruction (sputtering). This leads to instability of the recorded spectra and, accordingly, worsens the reproducibility of the measurement results, and also reduces the reliability of the long-term operation of the device.
- the technical result of the proposed method for emission analysis of the elemental composition of liquid media is to increase the stability and reproducibility of the measurement results, as well as the reliability of the long-term operation of the device.
- the technical result provides the proposed method for the emission analysis of the elemental composition of liquid media, including initializing a local electric discharge in the analyzed liquid with the formation of a conductive channel in the volume of the diaphragm hole made in the structural element of the electrolytic cell, and recording the emission spectra of the determined chemical elements - Comrade, in which, first, in the volume of the conductive channel, the determined elements are deposited at current, on which it is insufficient for initiating a local electrical discharge, then change the direction of current ement and increase its value to initialize the local electric discharge, and occurs at the same time in the test fluid The radiation is recorded to obtain emission spectra determined chemical elements.
- the determined elements are deposited at a current whose magnitude is insufficient to initiate a local electric discharge, then change the direction of the current and increase its value to initiate a local electric discharge , and the radiation arising in this case in the analyzed liquid is recorded to obtain emission spectra of the determined chemical elements.
- the value of the deposition current can be selected depending on the elements being determined and their concentrations in the liquid.
- FIG. 1 schematically shows a variant of the device for implementing the proposed method.
- FIG. 2 shows the spectra of tap water obtained:
- FIG. Figure 3 shows the spectra of a model solution containing 0.01 ppm of lead, copper, zinc, cadmium and 1 ppm calcium ions, obtained: a - using a local electric discharge as a source;
- emission analysis of the elemental composition of a liquid is carried out as follows.
- the volume of the electrolytic cell is filled with the analyzed liquid, in one of the structural elements of which a diaphragm hole is made with a small cross-sectional area and length that forms the diaphragm channel.
- Defined elements are deposited in the volume of the formed conductive channel by creating a current between the cell electrodes installed on different sides of the diaphragm opening.
- the magnitude of the current is insufficient to initialize the LER.
- an LER is initialized in the diaphragm channel, for which they change direction and increase the current between the electrodes.
- the light radiation arising from the LER is recorded with a spectrometer as an analytical signal to obtain emission spectra of the detected chemical elements.
- the value of the deposition current is selected depending on the elements being determined and their concentrations in the analyzed liquid. With the same set of determinable elements, the time spent on deposition, the greater, the lower their concentration.
- the device with which the proposed method is implemented comprises a housing 1 with a dielectric partition 2 separating its internal volume, in which a diaphragm hole 3 is made.
- electrodes 4a and 46 are placed, which are connected to a stabilized source 5 of high - straining.
- the housing 1 is filled with an electrolytic liquid 6, the elemental composition of which is subject to analysis.
- the spectrometer 7 is placed on the external side of the housing 1 in such a way as to be able to detect light radiation arising in the zone 8 of the electron beam laser.
- the walls of the housing 1 and the partition 2 are made of quartz glass.
- the thickness of the partition 2 from 0.2 mm to 1.5 mm.
- the area of the diaphragm hole 3 is determined based on the voltage across the electrodes 4a and 46, the thermal conductivity and electrical conductivity of the liquid 6 and the thickness of the dielectric partition 2.
- the diameter of the diaphragm hole 3 was from 0.1 mm to 0.05 mm, i.e., the volume of the diaphragm the channel was less than 0.1 cubic meters.
- mm High voltage source 5 provided voltage regulation from 0 to 10 kV and, for stabilization, was connected via a ballast resistance of 20 k ⁇ or more.
- the electrodes 4a and 46 are made of a corrosion-resistant material, in particular titanium with ruthenium oxide. To select the recorded radiation, a quartz fiber optic input installed in zone 8 of the LER was used.
- the device (Fig. 1) works as follows. High voltage from source 5 applied to electrodes 4a and 46 located in If the housing 1 is not analyzed by the liquid 6, it causes an electric current between them, which forms a conductive channel in the volume of the diaphragm opening 3.
- the magnitude of this current is sufficient to ensure effective mass transfer of impurities of the analyzed liquid 6 to the channel, and the time of its action is selected the more, the greater the sensitivity of the analysis must be ensured (that is, the lower the concentration of the detected elements in the analyzed liquid).
- the magnitude of this current is from 0.05 to 0.3 of the magnitude of the current LER, and its duration is about 30-500 seconds.
- the determined elements are deposited, after which the LER is initialized.
- the polarity at the electrodes 4a, 46 is changed and the voltage supplied to them is increased.
- a voltage in the range of values from 5 kV to 15 kV is required with a wall thickness of 2 from 0.2 mm to 1, 5 mm and a diameter of aperture 3 from 0.1 mm to 0.05 mm.
- This discharge being localized in a small volume of liquid located in the channel 3 of the dielectric partition 2, creates a high power concentration sufficient for ionization or atomization of the liquid and the deposited detectable elements.
- the resulting light radiation is recorded in zone 8 by a spectrometer 7 as an analytical signal for obtaining emission spectra of determined chemical elements.
- the voltage of occurrence (ignition) of the LER also depends on the conductivity of the analyzed liquid. For example, for a KC1 solution with a concentration of 0.0001 M to 0.1 M, the voltage of the occurrence of the LER varied from 3 kV to 10 kV. In this case, the voltage drop in the current-conducting channel was from 0.5 kV to 2 kV, and the current value was from 0.02 A to 0.1 A.
- the high voltage supply is provided by a high-voltage voltage source 5, the stabilization of the current of which is one of the conditions for the stability of the LER. Despite the high temperature, in the LER zone, Long-term and stable operation of the diaphragm opening 3 is achieved due to the intensive heat removal by the liquid 6.
- the spectrum of tap water (Fig. 2a) was obtained by directly initializing the LER without performing the deposition operation of the determined elements.
- the spectrum of tap water (Fig. 26) was obtained according to the proposed method, that is, with the initial operation of deposition of the elements being determined (within 150 s) and the subsequent initialization of the LER. In this spectrum (Fig.
