Abstract
An immunoassay for detecting total aldicarb in an aqueous sample suspected of containing the same is disclosed. In the inventive method, an oxidant is added to the aqueous sample, with the oxidant provided in an amount sufficient to oxidize all aldicarb contained in the solution to aldicarb sulfone. Next, the aqueous sample is combined with a thioether solution capable of neutralizing excess oxidant in the aqueous sample to thereby provide a neutralized test solution. The neutralized test solution is then contacted to an antibody capable of binding aldicarb sulfone, and the aldicarb sulfone bound to the antibody detected.
