Abstract
The present invention relates to a method for detecting content of water treatment cheemicals in industrial circulating water by adopting tracer substance belonging to the field of industrial water treatment and detection technology. Said invented method includes adding tracer substance into water treatment chemicals, adding the mixture into circulating water, determining fluorescent intensity of the tracer substance to quantitatively determine the content of water treatment chemicals in the circulating water, feeding said signal back into frequency variable chemicals-adding system and regulating dose so as to implement automatic addition of chemicals and continuous detection of circulating water.
Description
The present invention relates to a kind of method that adopts probe material to detect water treatment agent content in the industrial circulating water, belong to the Treatment of Industrial Water detection range.
Present domestic electric system, petrochemical system circulating water treatment are generally adopted phosphorus to be or be low-phosphorous is water treatment agent, phosphate radical (PO in the monitoring recirculated water
4 3-) content is as the controlling index of medicament in the recirculated water and the controlling index of medicament addition.Adopt manual analytical approach to carry out phosphate radical (PO in the recirculated water
4 3-) Determination on content, the experimental technique complexity needs to add medicaments such as the concentrated sulphuric acid, ammonium molybdate sulfuric acid solution, ascorbic acid, and phosphate radical (PO
4 3-) influence factor is many in the color development process, the method error and the personal error of introducing are bigger.Though phosphate radical (PO
4 3-) analysis meter dropped into commercial the use, it is still the same with manual analytical approach that it detects principle, needs to add various medicaments, and the instrument maintenance amount is big; A homemade phosphate radical (PO
4 3-) about 200,000 yuan of analyser, import instrument is about 600,000 yuan, costs an arm and a leg, and incompatiblely uses in circulation.
The purpose of this invention is to provide water treatment agent content detecting method in a kind of more simple industrial circulating water, realize continuous detecting, Automatic Dosing.
Employing probe material of the present invention detects the method for water treatment agent content in the industrial circulating water, be that probe material is added in the water treatment agent, make probe material and water treatment agent that a relatively-stationary proportionate relationship be arranged, together add in the recirculated water with water treatment agent, by measuring the fluorescence intensity of probe material, thereby measure the content of water treatment agent in the recirculated water quantitatively, and with signal feedback to the frequency conversion medicine system, adjustment adds dose, realizes Automatic Dosing, the continuous detecting of recirculated water.
Probe material itself does not have the effect of water treatment agent, and it self does not participate in reaction, can be in water long-time stable existence.Probe material has the characteristic of spike, by measuring its fluorescence intensity, can determine the content (G of probe material
1), and then the content of water treatment agent in definite recirculated water, that is:
G＝f
1(G

1＝f
2(F)
F=φ
f(I

f(1-10
-abc) wherein:
G: water treatment agent content in the recirculated water
ф
f: the quantum efficiency of fluorescence
F: fluorescence intensity
I
0: incident intensity
I: see through light intensity mensuration intensity of fluorescence and can be used for the many inorganic and organism of quantitative measurement, its advantage is highly sensitive, it measures lower limit than low two to four orders of magnitude of beam split photometry, and between 0.1～0.001mg/L, selectivity is also good than beam split photometry.
The present invention has the following advantages compared with prior art: detection method is simple, need not add oxygenant, colour former, reductive agent etc. in test solution, can determine the content of water treatment agent by the fluorescence intensity of measuring slight trace material in the recirculated water.Because it is different to detect principle and classic method, instrument and equipment is simple, sensitivity, accuracy height, and maintenance work is little, realizes Automatic Dosing, the continuous detecting of recirculated water easily.
Embodiment:
The ratio of probe material (this experiment is adopted fluorescein as probe material) according to 0.5% added in the recirculated water water treatment agent, then water treatment agent is added the fluorescence intensity that detects in the recirculated water in the recirculated water.The fluorescence intensity formula is expanded into:
F=I
0ф
f(1-10
-abc)=I
0ф
f(2.3abc-(2.3abc)
2/ 2!-(2.3abc)
3/ 3! ) since in the recirculated water probe material concentration very rare, project on the solution absorbed exciting light less than 2%, i.e. abc=A＜0.05, following formula can be reduced to:
F=2.3 ф
fAbcI
0Keep excitating light strength I
0Necessarily, then have:
F=k
1 *The content G (mg/L) of water treatment agent is in c so the recirculated water:
G=k
*(F: with respect to the intensity of blank solution, %) can be got by testing result: when G=0.182F was 25% when fluorescence intensity, water treatment agent content was 4.55mg/L to F in the recirculated water, and is consistent with manual analytic approach measured result.With the detection signal control of conversion medicine system of fluorescence detector, realize the Automatic Dosing of recirculated water medicament.
