摘要
对示波伏安滴定装置进行了改进;提出了示波微分伏安滴定法;用EDTA及EGTA滴定了Zn^(2+)、Ga^(2+)、Cd^(2+)、Ni^(2+)和Co^(2+)等离子。实验结果表明:新方法灵敏度高、准确性好。
A new method called oscillographic differential voltarnmetric titration is presented. In the method, the circuit of oscillographic voltarnmetric titration was improved. By using the way.Zn2+ ,Cd2+ ,Ga3+ , Ni2+ , and Co2+ were directly titrated with EDTA or EGTA. The experimental result shows that sensibility and accuracy of the method are better than those of oscillographic voltarnmetric titration.
