摘要
本文用校正矩阵计算滴定法,同时测定二、三和四元金属离子混合物。讨论了计算原理和实验方法,选择了最佳实验条件。对二、三和四元混合离子溶液进行了上百次测定,结果可达到化学分析准确度的要求。用本法测定难以分离和分离过程复杂的元素,有明显优点;测定一般元素,也具有省时、省力的特点,是很有应用前景的方法。
In this paper the simultaneous determination of multicomponent metal ions has been investigated by calibrated matrix calculation-titration method. The optimum conditions for simultaneous potentiometric titration have been established. Three demonstrations of this method for the determination of mixed metal ions,such as binary and ternary and quaternary, are given and the results are satisfactory.
