摘要：

A flow-injection method is described for the simultaneous determination of copper and zinc with a single detector using the pH gradient technique. Zincon is used as the colour reagent for the spectrophotometric determination. The linear range for the determination of zinc is 0.4-12 mu g ml(-1) and for copper is 0.1-3.0 mu g ml(-1). About 20-30 samples can be determined in one hour, The proposed method has been applied to the determination of zinc and copper in chiIdrens' hair.
