Abstract

The invention discloses a water quality detection agent for detecting a chromium element in water. The water quality detection agent comprises, by weight, 30-50 parts of modified absorbents, 20-30 parts of chromium adsorption fillers, 4-6 parts of ethylene diamine tetraacetic acid, 5-15 parts of ammonia water, 3-9 parts of potassium iodide, 2-5 parts of sodium sulfite, 4-8 parts of nano-scale ceramic powder, 3-9 parts of ammonium citrate, 2-6 parts of dimethylglyoxime, 1-5 parts of hexadecyl dimethyl ethyl ammonium bromide, 2-7 parts of linoleic acid glyceride, 3-8 parts of dimethylol dimethyl hydantoin and 10-20 parts of ethyl alcohol. The water quality detection agent can adsorb chromium elements in water, the content of the chromium elements in water is detected, and chromium element detecting efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of water quality detection agents, in particular to a water quality detection agent for detecting chromium in water. Background technique [0002] Industries such as electroplating, tanning, mining and dyestuffs produce a large amount of chromium-containing wastewater, which leads to a series of environmental problems. Chromium is highly toxic and penetrating, so it is very easy to pollute groundwater. Hexavalent chromium compounds are pollutants with carcinogenic, teratogenic and mutagenic effects, and the discharge of wastewater containing hexavalent chromium compounds is extremely harmful to humans and the environment. In the process of water quality testing, the detection of chromium is an important element detection, but the detection efficiency and accuracy of the water quality detection agents in the existing technology cannot meet the needs of actual operation, so it is urgent to design a kind of A...
