中文摘要	Potentiometric sensors have evolved to be a promising tool for environmental trace analysis and potentiometric biosensing. However, the applications of potentiometric sensors are restricted to measurements of samples without complex matrixes. A new potentiometric detection system for detection of trace-level chlorpyrifos (CPF) in real samples is described in this paper. By using on-line molecularly imprinted solid-phase extraction (MISPE), interferences from sample matrixes can be effectively eliminated. Numerous key variables including affecting the extraction recovery of MISPE have been optimized. The proposed detection system offers a low detection limit of 0.027 nmol L-1 and exhibits excellent selectivity over other organicphosphate pesticides such as parathion-methyl, phoxim and dipterex. The practical application of the proposed system has been carried out for detection of CPF at trace levels in real seawater samples.
