Abstract:

Using tribenuron-methly as a template molecule and N,O-bismethacryloyl ethanolamine as a functional linked monomer, a molecularly imprinted membrane over a Nylon-6 support was prepared by UV irradiation. The surface of the molecularly imprinted membrane was studied by scanning electron microscopy. The interaction between the template molecule and the functional linked monomer was evaluated by UV spectrophotometric method. The permeation experiments throughout the imprinted membrane and non-imprinted one were carried out with the mixed solution containing template and its competitive analogues. The imprinting factors were also determined. These results show that the molecularly imprinted membrane exhibit higher transport selectivity for the template molecule tribenuron-methly than those of its analogues chlorimuron-ethyl and thlfensulfuron-methy. But the non-imprinted membrane has no permselectivity for the three substrates.
