铜离子选择电极已广泛用于水、合金、矿石、土壤、电镀液和催化剂中铜的测定。由于多次添加法的精度较高,适于复杂组分的测定,所以作者应用连续多次添加技术分别测定了铝合金标样和未知铝合金试样中的铜,并与铜试剂比色法进行了比较,结果较好。本文应用二分法解有关浓度变量N_l的超越方程,并编制了BASIC程序和框图。
Copper ion selective electrodes have been widely used in the determination of copper in water, alloys, ores, soils, baths and catalysts. Due to the high precision of the multiple addition method, which is suitable for the determination of complex components, the authors used multiple successive addition techniques to determine the copper in the aluminum alloy standard sample and the unknown aluminum alloy sample, respectively, and compared with the copper reagent colorimetric method Compared, the result is better. This paper applies dichotomy to solve the transcendental equation of concentration variable N_l, and compiles the BASIC program and block diagram.
