Abstract

The invention discloses a water quality detection agent for detecting lead element in water. The raw materials include 60-80 parts of modified adsorbent, 25-45 parts of modified adsorption enhancing filler, and 4-8 parts of polyacrylamide in parts by weight. , 2-6 parts of epichlorohydrin, 3-6 parts of ferrous sulfate, 6-9 parts of disodium edetate, 1-4 parts of ammonia water, 2-3 parts of potassium iodide, 5-8 parts of sodium sulfite, nano-scale 1‑3 parts of ceramic powder, 9‑12 parts of ammonium citrate, 6‑8 parts of dimethylglyoxime, 5‑9 parts of hexadecyldimethylethylammonium bromide, 0.5‑1.5 parts of glyceryl linoleate , 1.5-2.5 parts of dimethylol dimethyl hydantoin, 25-35 parts of ethanol. The water quality detection agent of the present invention can perform adsorption detection on the lead element in water, and can effectively improve the efficiency and detection accuracy of water quality detection.

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 lead in water. Background technique [0002] Lead, a heavy metal, is a highly toxic substance that can cause adverse effects on many organs of the human body, especially the lungs, kidneys, reproductive system, and cardiovascular system. With the acceleration of industrialization and the continuous development of urban modernization, a large amount of lead-containing wastewater enters the water environment, which has caused serious deterioration of the aquatic ecological environment. Therefore, the lead content in wastewater must be strictly controlled to reduce its environmental pollution. In the process of water quality detection in the prior art, the detection of lead element is one of the key detection items in the detection project, and the detection efficiency and accuracy of the detection result of the water q...
