目前,已试制出各种类型的铜离子选择电极。本文报告用CuTe-Ag_2S制备的铜离子选择性电极测定铜的方法。研究了电极的使用条件和干扰的消除,用于一些矿石和土壤中铜的测定,结果和铜试剂比色法一致。实验部份铜离子选择性电极系本校化工厂试制,将其插入样品溶液,用双液接盐桥与饱和甘汞电极连接,组成测量电池。以pHS-2型酸度计和UJ-25型高电势直流电位差计联用测定该电池的电动势。为了保
At present, various types of copper ion selective electrodes have been fabricated. This paper reports a method for the determination of copper using a copper ion selective electrode prepared with CuTe-Ag_2S. Electrode conditions and interference elimination were investigated for the determination of copper in some ores and soils, consistent with the copper reagent colorimetric method. Experimental part of the copper ion selective electrode Department of the chemical plant trial production, will be inserted into the sample solution, with a two-salt salt bridge saturated calomel electrode connected to form a measurement of the battery. The electromotive force of the battery was measured in combination with a pHS-2 type acid meter and a UJ-25 type high potential DC potentiometer. To protect
