METHOD FOR OXIDIZING LIQUID-PHASE NEUTRALIZATION OF NITROPHENOL PESTICIDES AND NITROGEN-CONTAINING HETEROCYCLIC COMPOUNDS

摘要

FIELD: environmental protection.;SUBSTANCE: method involves providing neutralization of pesticides and nitrogen-containing heterocyclic compounds with the use of oxidizing system generated on passage of direct electric current having density of up to 1 A/cm² through solution, suspension or emulsion in sulfuric acid; performing said process in diaphragm-free electrode apparatus in sulfuric acid solution concentrated to 10-96% while intensively mixing at temperature of from 25 C to solution boiling temperature for 90-300 min under atmospheric pressure.;EFFECT: increased efficiency in neutralization of nitrophenol pesticides and nitrogen-containing heterocyclic compounds.;1 tbl, 1 ex
