Abstract
The invention discloses the reagent combination that a kind of underwater trace chlorion is measured, comprising by percentage is the ammonium nitrate of the sodium carbonate of 10-60%, the ammonium sulfate of 20-65%, the mercuric thiocyanate of 10-30% and 5-10%.The present invention can directly be dissolved in the water (medicament originally must with the organic solvent dissolutions such as methyl alcohol), and toxicity is low, and the sensitivity of measuring chlorion significantly improves.
Description
Technical field
The present invention relates to a kind of reagent combination, be specifically related to the reagent combination that a kind of underwater trace chlorion is measured.
Background technology
The mensuration of trace chloro ion is the important indicator of Power Plant Water Vapor supervision, but in steam, the detection of (0-1) mg/L chlorion can only use the chromatography of ions.This instrument mainly relies on import, expensive and be difficult to realize on-the-spot on-line determination, and most of power plant cannot be equipped with ion chromatograph due to price reasons, is unfavorable for power plant's Timeliness coverage Resolving probiems problem.Chlorine ion content determination method one mercuric thiocyanate spectrophotometric method in the steam of power industry standard DL/T1203 fuel-burning power plant has been formulated in order to address this problem, but this standard uses the mercuric thiocyanate that developer is severe toxicity, it is poorly soluble, ethanol or methanol solution can only be dissolved in, placed of a specified duration and can produce precipitation, and the blank absorbency of colorimetric is high; During for on-line measurement chlorion, the organic solvent dissolving mercuric thiocyanate can volatilize in system, and make pipeline variable color and produce bubble, affect the accurate calculating of chemical feeding quantity, the application of method is restricted.
Summary of the invention
The object of the invention is to the shortcoming overcoming above-mentioned prior art, provide the reagent combination that a kind of underwater trace chlorion is measured, this medicament can directly be dissolved in the water, toxicity is low, and measures the highly sensitive of chlorion.
For achieving the above object, the reagent combination measured of underwater trace chlorion of the present invention by be the sodium carbonate of 10-60% by percentage, the ammonium nitrate of the ammonium sulfate of 20-65%, the mercuric thiocyanate of 10-30% and 5-10% forms.
The medicament that described underwater trace chlorion is measured is water soluble medicament, and changing the original mercuric thiocyanate that uses can only be dissolved in the organic solvents such as methyl alcohol, and the toxicity of medicament reduces greatly.
The present invention has following beneficial effect:
The reagent combination that underwater trace chlorion of the present invention is measured is made up of sodium carbonate, ammonium sulfate, mercuric thiocyanate and adjuvant, directly can be dissolved in the water, toxicity is low, can measure the chlorion in Power Plant Water Vapor accurately, reagent combination can be promoted the use of in each power plant.

The compound prescription that the present invention develops can be used for the chlorion of (5-1000) μ g/L in Accurate Determining Power Plant Water Vapor, measures chloride test sensitivity and significantly improves; Medicament is water soluble medicament, and solubleness is high, uses more convenient, and new prescription medicament toxicity significantly reduces, and the reagent combination that described underwater trace chlorion is measured is water-soluble, and changing the original mercuric thiocyanate that uses can only be dissolved in the organic solvents such as methyl alcohol.
Detectability and sensitivity technique
The reagent combination adopting mercuric thiocyanate and underwater trace chlorion of the present invention to measure detects chlorion, and measurement result is in table 1:
Table 1
Above-mentioned demonstration test result shows, chloride test lower limit by 20 original μ g/L to 5 μ g/L, is achieved good concentrated effect and measurement effect by the reagent combination that underwater trace chlorion of the present invention is measured.
Dissolubility detects
The reagent combination that underwater trace chlorion of the present invention is measured is water miscible, and the mercuric thiocyanate originally used only can the organic solvent such as solution and methanol or ethanol.The invention solves the problem that mercuric thiocyanate is poorly soluble, placed to produce precipitation precipitation of a specified duration.The problem that in simultaneously original chlorion on-line measurement instrument pipeline, bubble is many, volatility is large is also resolved, and when making chlorion on-line measurement, chemical feeding quantity is more accurate, and measurement result is also more accurate.
Toxicity detection
The toxicity of the reagent combination that underwater trace chlorion of the present invention is measured and mercuric thiocyanate contrasts as shown in table 2:
Table 2
As shown in Table 2, the reagent combination that underwater trace chlorion of the present invention is measured reduces greatly relative to mercuric thiocyanate toxicity.
