摘要：

The membrane coated with enzyme of plant origin or other chemical compounds has been prepared for the extraction of trace organophosphorus pesticides and their intermediates in water. The extraction efficiencies of different membranes were compared. The glutaraldehyde membrane was used for determining thiophosphoramidic acid trimethyl ester and spermine in a river water survey. The recoveries of surrogates were between 68% similar to 103% and the detection limit was as low as 0.1 mug/L.
