摘要：

An on-line continuous-flow solvent extraction system has been developed. The method consists of a segmentor, an extraction coil, a phase separator, a switching valve, and a pumping system. The performance of the system was illustrated by extracting copper with a solution of zinc diethyldithiocarbamate in chloroform. Parameters affecting proconcentration of the analyte in the system were examined. The method can be used for quantitative analysis and as a preparative technique.
