Abstract

The invention discloses a scavenging agent for removing heavy metal cadmium in building waste.The scavenging agent is prepared from, by weight, 2-8 parts of 3-exo-aminobicyclo[2.2.1]hept-5-ene-2-exo-carboxamide, 10-25 parts of ethylene oxide, 3-8 parts of 2,2'-[(dioctylstannylene)bis(thio)]bis-acetic aci diisooctyl ester, 5-12 parts of 3-Methyl-5-(5-methylisoxazol-3-yl)isoxazol-4-carbonylchloride, 4-10 parts of ethyl acrylate and 2-dimethylaminoethyl methacrylate copolymer, 10-22 parts of ammonia water and 1.5-5 parts of 1-[(triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1h)-one.The scavenging agent for removing heavy metal cadmium in building waste is low in cost, processing is easy, drying speed is high, and the antioxidant capacity is high.

Description

technical field [0001] The invention relates to a scavenger for removing heavy metal cadmium in construction waste and a manufacturing method thereof, belonging to the field of chemical industry. Background technique [0002] Cadmium is not an essential element for the human body. Cadmium is highly toxic and can accumulate in the human body, mainly in the kidneys, causing functional changes in the urinary system. Cadmium can replace calcium in bones, causing serious softening of bones and broken bones, causing stomach dysfunction, interfering with the enzyme system of zinc in the human body and organisms, leading to increased hypertension. When the water contains 0.1mg / L cadmium, it can slightly inhibit the self-purification of surface water. The safe concentration of cadmium to silver carp is 0.014mg / L. When the water containing cadmium 0.04Mg / L is used for irrigation, the soil and rice are obviously Pollution, when the cadmium in agricultural irrigation water is 0.007mg / ...
