Prefabricated reagent for water quality detection

Abstract

The invention relates to the field of water quality detection, in particular to a water quality detection prefabricated reagent. The water quality detection prefabricated reagent provided by the invention is prepared from the following components in parts by weight: a reagent A and a reagent B. The reagent A is prepared from 10-25 parts of potassium dichromate, 3-8 parts of concentrated sulfuric acid, 5-8 parts of mercury sulfate and 3-15 parts of distilled water, and the reagent B is prepared from 2-8 parts of silver sulfate and 3-15 parts of concentrated sulfuric acid. Compared with the prior art, the reagent provided by the invention has the advantages that the COD content in water can be effectively detected, the detection sensitivity is relatively high, and the reagent provided by theinvention is produced on a large scale, so that the stability of the reagent quality between batches can be well guaranteed, and the detection result is more reliable. Besides, the water quality detection reagent provided by the invention is low in price, can be quickly degraded and settled after detection, does not cause secondary pollution to a water body, and is convenient for large-scale popularization.

Description

technical field [0001] The invention relates to the field of water quality detection, in particular to a prefabricated reagent for water quality detection. Background technique [0002] Water is the source of life, and the quality of water directly affects the health of all people and all aspects of life. It can be said that the level of water quality directly affects the living standards of all water users. [0003] Especially in today's social situation, the industry is developing rapidly, and problems such as sewage discharge always exist. In the process of sewage testing, COD is an important indicator that needs to be tested in order to evaluate the organic matter content in sewage. In the prior art, the COD detection is mostly done by the laboratory, and the experimenters design the experimental sequence according to the water body conditions, and finally obtain the COD content result. [0004] This process is relatively cumbersome, and the stability of the reagent is...

AI Technical Summary

Problems solved by technology

[0004] This process is relatively cumbersome, and the stability of the reagent is greatly affected by the operator's own operating level, so that the test results cannot reflect the real situation well.

In addition, the configuration process of detection reagents also requires experimenters to come into contact with a large number of chemicals, which poses many potential safety hazards.
