Abstract: With monosulfuron as the template molecule, a molecularly imprinted polymer (MIP) was prepared and used as the solid-phase extraction material in the environmental analysis. Recognition properties of the monosulfuron imprinted polymer were studied by equilibrium adsorption and HPLC. The influence of various chromatographic conditions on the retention factors of monosulfuron was also evaluated. It was found that recognition properties of MIPs are greatly influenced by the mobile phase used. The results show that the imprinted polymer has good affinity and marked selectivity for monosulfuron, and it can selectively retain the template and separate the soil impurities from monosulfuron. This implies that it can be used as a solid-phase stationary material for sample enrichment and cleanup in the analysis of monosulfuron residues in soils. (Analytical Abstracts 2005)
