Abstract
The utility model provides a mercury tester which can be used for testing micro mercury content in liquor sample. A low pressure mercury lamp is arranged in a light shield. The light shield is provided with a vertical and narrow slit. Light rays of the low pressure mercury lamp can be emitted from the slit. A reduction bottle is arranged on one side of the low pressure mercury lamp which is arranged in the light shield. The slit on the light shield is corresponding to the reduction bottle. The reduction bottle is filled with photochemistry reductant. The reduction bottle is connected with the mercury tester by an air inlet pipe and an air outlet pipe. The mercury tester utilizes photochemical methods to test mercury content. The utility model has the advantages of simple structure and low cost, and does not need non-toxic reagent in the process of test. The mercury tester can conveniently and quickly test the low mercury content in liquor sample.
Description
Technical field
The utility model relates to a kind of hg determining device that mercury content in the liquor sample is measured.
Background technology
Enhancing along with people's awareness of environment protection and health, everybody is more and more higher to the requirement of mercury pollution detection means, and the determination and analysis of mercury all plays crucial effects to mercury Biochemical Mechanism, the research of toxicity and the geochemistry circulating research of global mercury in vivo.At present, thus the various forms of mercury all are to realize the quantitative test of each form mercury by the design of concentration and separation, analytic process in the water environment.Analyzing detecting method commonly used mainly contains atomic fluorescence spectrometry, atomic absorption spectrography (AAS), spectrophotometric method, hydride atomic fluorescence spectrometetry etc., but when measuring micro-mercury content with these methods, all there are some problems, can not make things convenient for, environmental protection, apace low mercury content in the liquid solution be measured.
Summary of the invention
In order to overcome the deficiencies in the prior art; the utility model provides a kind of hg determining device that uses photochemical reduction method to measure mercury content; in the process that this apparatus structure is simple, with low cost, measure required reagent nontoxic, can measure low mercury content in the liquor sample easily and quickly; also can be widely used in of the assay determination research of aspects such as environmental protection, medical and health, Food Inspection, geologic prospecting and chemical research simultaneously to measuring through handling the solid and the gas sample that are converted into solution to Trace Mercury.
The technical scheme that its technical matters that solves the utility model adopts is: mercury lamp is placed in the light shield, light shield is provided with vertical, a narrow slit, light for mercury lamp penetrates by slit, the reduction bottle is positioned at a side of the mercury lamp that places light shield, slit on the light shield is relative with the reduction bottle, the agent of dress photoreduction is reduced between bottle and the mercury vapor analyzer by coupling together into and out of tracheae in the reduction bottle.
As shown from the above technical solution, in this device equipment such as used mercury lamp, reduction bottle all be simple and easy to and cheap, agents useful for same is nontoxic, can not cause environmental pollution.And this device is to utilize photoreduction agent photodissociation under the irradiation of mercury lamp to produce reductive free radical Ox
-(C

2+The mode of carrying out photoreduction is measured the content of mercury.Its mensuration process is fairly simple, fast, and environmental protection; Its measurement result is more accurate, directly perceived.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Fig. 2 is that Figure 1A-A is to view.
Among the figure 1, mercury vapor analyzer, 2, mercury lamp, 3, light shield, 4, the reduction bottle, 5, draft tube, 6, escape pipe, 7, slit.
Embodiment
As Fig. 1, shown in 2, mercury lamp 2 places in the light shield 3, it is one vertical that light shield 3 is provided with, narrow slit 7, light for mercury lamp 2 penetrates by slit 7, use low pressure mercury lamp just passable generally speaking, reduction bottle 4 is positioned at a side of the mercury lamp 2 of light shield 3, slit 7 on the light shield 3 is relative with reduction bottle 4, distance between reduction bottle 4 and the mercury lamp 2 can be regulated, the reduction bottle 4 general quartz glasss of using are made, be marked with scale on it, dress photoreduction agent in the reduction bottle 4, the photoreduction agent can be selected iron chloride and sodium oxalate system or other photoreduction agent system for use, reduce between bottle 4 and the mercury vapor analyzer 1 by advancing, escape pipe 5,6 couple together, for making measurement result more accurate, intuitively, mercury vapor analyzer 1 generally selects for use numeral to show mercury vapor analyzer, and available model is that the numeral of F732-G shows mercury vapor analyzer.
When using this device to measure mercury content, be ready to detected solution and photoreduction agent at first on request, then the F732-G numeral is shown that mercury vapor analyzer regulates duty, open the mercury lamp power supply again, regulate quartz glass reduction bottle and arrive suitable distance with mercury lamp, the preheated one-section time, treat instrument stabilizer after, measure.
The typical curve related coefficient that shows this hg determining device by experiment can reach 0.9993, and the coefficient of variation only is about 2.4%, and the device detectability is good.
Claims (4)
1, a kind of hg determining device, at least comprise mercury vapor analyzer, mercury lamp and reduction bottle, it is characterized in that: mercury lamp is positioned at light shield, light shield is provided with vertical, a narrow slit, the reduction bottle is positioned at a side of the mercury lamp of light shield, slit on the light shield is relative with reduction bottle, a dress photoreduction agent in the reduction bottle, between reduction bottle and the mercury vapor analyzer by being connected into and out of tracheae.
2, hg determining device according to claim 1 is characterized in that: the photoreduction agent of dress is iron chloride and sodium oxalate system in the reduction bottle.
