摘　　要：在氨性介质中,邻菲啰啉与Cr(Ⅵ)有一峰电流较大的催化波,Cr(Ⅵ)浓度在0.006～0.16μg/ml范围内与峰电流呈线性关系,检测限为7.7×10^(-8)mol/L,该法可用于矿石和水样中Cr的测定。The Cr-o-phenanthroline complex produces a highly sensitive catalytic polarographic wave in am-moniacal sodium nitrite system. There is a linear relationship between the peak current and the Cr( Ⅵ ) concentration in the range 0. 006 ~ 0. 16μg/ml, the detection limit being 7. 7 × 10-8mol/L. The method has been used to the analysis of ore and water samples.
