摘要
基于酸碱滴定通式,提出了用最小二乘法处理电位滴定数据,求算混合酸组分浓度的通用分析方法。测定了几种不同类型的混合酸样品,平均相对误差为2%。
Based on the general equation of acid-base titration,the least square method is used for calculating the concentrations of mixed acids.The method is simple and suit- able for determining different kinds of samples.The titration is performed potentiometri- tally,several examples are given and the analytical results are with an average relative error of 2%.
