摘要
将校正矩阵计算法用于单点ｐＨ络合滴定法中，同时测定了镍矿中Ｎｉ，Ｃｕ，Ｃｏ含量。讨论了方法原理，指定ｐＨ值的选择及常数矩阵的建立。对７个自配样和镍精矿标样进行了测定，均获得满意结果。
This article applies correctional matrix calculation to single-point pH complexometry for determination of Ni,Cu,Co contents in nickel minerals simultaneously and the article discusses method principle,determination of appointed pH,institution of constant matrix,Seven mixed samples and mineral samples and concentrate standard samples are determined and satisfactory results are obtained.
