摘要
在pH5 5的HAc -NaAc -抗坏血酸 -KI溶液中 ,用单扫描示波极谱法获得镉与KI络合物极谱吸附波 ,其峰电位在 -0 73V( vs SCE) ,镉在 0 4～ 80 μg/5 0mL范围 ,峰电流与镉的浓度呈良好的线性关系 ,方法用于金属锌中镉的测定 。
A polarographic adsorptive wave of Cd KI complex was obtained by using single sweep polarography in the solution of HAc NaAc ascorbic acid KI at pH5 5 The peak potential is -0 73V(vs SCE) The linear relationship between the peak height and the concentration was found in the range of 0 4-80μg/50mL for Cd The method has been applied to the determination of cadmium in zinc with satisfactory results
