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 formula of acid - base titration, a general analytical method for calculating the concentration of mixed acid components by potentiometric titration data by the least square method is proposed. Several different types of mixed acid samples were measured with an average relative error of 2%.
