Use of XAD-2 Macroreticular Resin for the Recovery of Aldicarb and its Metabolites in Drinking Water

摘要

A simplified method for the determination of aldicarb and its oxidation products, aldicarb sulfoxide, and aldicarb sulfone, in water has been developed. Aldicarb and its metabolites are adsorbed on Amberlite XAD-2 polymer resin and then eluted with acetone. The eluate is analyzed for aldicarb and aldicarb sulfoxide by high performance liquid chromatography (HPLC) with UV detection at 254 nm. Total aldicarb residues can be determined by a colorimetric method. Typical detection limits in drinking water are 1 #x3BC;g/1.
