设计制作了用于改换介质的简易电解池，并以旋转圆盘玻碳电极为工作电极，研究了其用于电位溶出分析改换溶出介质的可行性。以同时测定Ｐｂ２＋ 、Ｃｄ２＋ 为例，试验了改换溶出介质的条件。结果表明，改换介质可消除共存离子的干扰，只要选择合适的溶出介质，可有效地提高测定方法的分辨率和灵敏度。此方法用于矿样中铅和镉的同时测定，结果满意。
The simple electrolytic cell used to change the medium was designed and manufactured. The feasibility of using the rotating disk glassy carbon electrode as the working electrode to study the potential dissolution analysis to change the dissolution medium was studied. Taking the simultaneous determination of Pb2 + and Cd2 + as an example, the conditions for changing the dissolution medium were tested. The results show that changing the medium can eliminate the interference of coexisting ions, so long as the suitable dissolution medium is selected, the resolution and sensitivity of the determination method can be effectively improved. The method is applied to the simultaneous determination of lead and cadmium in ore samples with satisfactory results.
