Decomposition of DDVP by Electrolyzed Water

The decomposition of DDVP, organophosphorous pesticide, mixed with acidic or alkaline electrolyzed water produced by the electrolysis of a 100 mM sodium chloride solution was investigated. As a result, it was found that 99.4∼99.5 % of DDVP decomposed and disappeared, a half of DDVP mineralized to CO2 only mixing with acidic electrolyzed water. In case of alkaline electrolyzed water, it was found that 100 % of DDVP decomposed and disappeared but did not mineralize to CO2. It is suggested that electrolyzed water is one of useful technique as means of the organophosphorous pesticide decomposition in the environmental field.
