Description
Technical field
The present invention relates to pesticide waste liquid processing technology field, specially a kind of processing method of Cupric sulfate centrifugation waste liquid.
Background technique
Cupric sulfate, dimehypo are nereistoxin bionic pesticides, belong to moderate toxicity, commodity are often with soluble powder, particle
The dosage forms such as agent, aqua exist.It is mainly used in the prevention and treatment of field rice snout moth's larva, rice-stem borer, three can be effectively prevented
Change snout moth's larva, rice leaf roller, while having favorable effect to rice leafhopper, lice, rice plant skipper, fruit aphid etc.；In vegetables, fruit tree, sweet
Sugarcane, wheat, corn, tealeaves, the pest controling effect on Chinese herbal medicine are also preferable.
Preparing the core scheme of Cupric sulfate at present is：
(CH3)2NCH2CHClCH2Cl·HCl+Na2S2O3→(CH3)2NCH(CH2S2O3Na)2
(CH3)2NCH(CH2S2O3Na)2+HCl→(CH3)2NCH(CH2S2O3H)CH2S2O3Na
I.e. alkene generates dichloro after completing chlorine addition, generates dimehypo, dimehypo and salt with sodium thiosulfate vulcanization reaction
Cupric sulfate can be obtained in acid acidification, control pH crystallization.
