PESTAB. A procedure for the isolation of aminocarb (4-dimethylamino- m-tolyl methylcarbamate) and its phenolic carbamate (aminocarb phenol, (4-dimethylamine- m-cresol)) from aqueous solution is described. An amberlite XAD-2 resin column was used for adsorption of aminocarb residues, and gas-liquid chromatography in N mode was used for final quantitation of aminocarb and its phenol metabolite. Fortified samples of potable water, river water, and buffer solutions ranging from pH 3.0-9.0 were analyzed. Results indicate that adsorption of the chemicals was pH dependent, with maximum aminocarb adsorption at pH 7.5 and above. The parent material was found to be stable on the column for 2 wk; the method serves as a preservation technique for aminocarb present in environmental waters. In samples fortified with 0.01 ppm aminocarb, percent aminocarb recoveries after 7 days were 98% from river water and 100% from potable water. The procedure is suggested to be readily applicable to environmental monitoring and quality control programs.
