摘　　要：为了监测中性及碱性土壤中矿物质的变化 ,同时避免Pb对水土的污染 ,研制了CuS电极 ,以代替Pb电极测量土壤电位。介绍了CuS电极的制备方法 ,对Cu、CuS、Pb、Ag、C、Pt等 6种电极在不同pH值及不同SO2 -4、Cl-、NO-3 、HCO-3 、CO2 -3 浓度条件下的稳定性以及随温度的变化情况作了比较 ,并对CuS和Pb电极的稳定性进行了实地测试。In order to monitor the change of minerals in neutral and alkaline soils and to avoid contamintion of water and soil by Pb, a CuS electrode has been prepared as a substitute for Pb electrode to measure the potential of soil.The preparation method is described.The stabilities of Cu,Pb,Ag,C,Pt and CuS electrodes were invesigated under different pH values,different temperatures and different concentrations of SO 2- 4,Cl -,NO - 3,HCO - 3 and CO 2- 3.
