ABSTRACT:
A method for detoxifying substituted and unsubstituted phosphonothiolates and phosphonothioic acids. The method requires reacting the phosphonothiolate or phosphonothioic acid with a sufficient amount of a compound containing an HSO.sub.5 -ion, for a sufficient time and under conditions sufficient to produce a reaction product having less toxicity than the phosphonothiolate or phosphonothioic acid. The preferred compound containing an HSO.sub.5 -ion is potassium monopersulfate, 2KHSO.sub.5.KHSO.sub.4.K2S0.sub.4.
