A Chlortoluron Sensor based on Molecularly Imprinted Sensitive Membranes

Molecularly imprinted polymer (MIP) was prepared by a reaction among template molecules of chlortoluron, functional monomers of methacrylic acid, and a crosslinker of N,N'-methylenebisacrylamide. Chlortoluron could be analyzed in the range of 0 to 3.0 x 10(-6) mol L-1 with a detection limit of 2.21 x 10(-8) mol Water samples were assayed and recoveries were obtained, ranging from 99% to 102%.
