摘要
本文提出了计算副反应系数α的新方法。如果给定的pL与系列lgK_n中任何一个lgK之差都在1.3上,则lgαM(L)=lgβ_i-ipL。i是系列lgK_n中大于等于pL的lgK的数目。如果pL与某个lgK_i之差小于等于1.3(|lgK_i)-pL|A≤1.3),则须附加相应的修正项。即lgαM(L)=lgβ_i-ipL+lg(10~A+1)/10~A。
A new equation for calculating the side reaction coefficient ~αM(L) in the complexometric titration has been derived. If the difference between the pL and lgK in a series of lgK_n is larger than 1.3, then lgαM(L)=lgβi-ipL, where i is the number of lgK, in a series of lgK_n larger than the pL. But if the bifference between the pL and any lgK is smaller than 1.3 (means A≤1.3), the correction terms, i.e. lgαM(L)=lgβi-ipL+lg (10~A+ 1)/10~A, have to be used.
