Pesticide detoxifying functions of N-halamine fabrics.
Halamine structures incorporated on polyester/cotton fabrics were able to detoxify oxime carbamate pesticides that contain thio bonds rapidly upon contact. The reaction was endothermic, and the detoxification rate was in first order to concentrations of the pesticides. Aldicarb was degraded in a much faster rate than that of methomyl by the halamine fabrics. The reactivity of halamine structures was different, and imide halamine was more reactive than amine halamine. The detoxification was an oxidative reaction on the sulfur atom existing in both aldicarb and methomyl. The same halamine structures were unable to effectively react with carbaryl and carbofuran, which are aromatic carbamates and do not contain any thio bonds.
