Abstract: 2,4 - Dichlorophenoxyacetic acid (2,4-D) molecularly imprinted polymer (2,4 - D MIP) was prepared by using 2,4-D as template molecule. By means of streaming potentiometry, the associativity, selectivity, stability of 2,4-D MIP have been investigated. The results obtained showed that the 2,4-D MIP has good recognition ability for 2,4-D molecule and stable performances. After used for four months, the performances of imprinted polymer have no change. The relationship between the concentration of 2,4-D in mobile phase and streaming potential has been studied. It is possible that the microanalysis of 2,4-D in the environment by combining molecular imprint technique with streaming potentiometry.
