Abstract

In this paper, the in vitro degradation kinetics of dichlorvos (DDVP) was studied, and antidotes for hydrolyzing and oxidizing DDVP were selected. The results showed that the half-life of 2% sodium bicarbonate hydrolyzed DDVP commonly used in clinical gastric lavage was 20 hours. 1:5000 potassium permanganate aqueous solution oxidizes DDVP with a half-life of 0.5 minutes. Potassium permanganate is a highly effective antidote and is recommended as gastric lavage for poisoned patients.
