| Abstract: | A method of on-line column preconcentration and determination of trace cadmium by flow injection-atomic absorption spectrometry has been developed.In the chromatographic column 2-mercaptobenzothiazole and 8-hydroxy-quinoline are used as a stationary phase, and active silica gel is used as a carrier. The method has been used for determination of trace cadmium in environmental water with satisfactory results, the coefficient of variation and the detection limit are 1. 3% and 0. 01 mg/L, respectively. |
