| Abstract: | Based on related complex equilibria and material balances, a complexometric titra-tion in combination with indirect polarography and linear regression is proposed to widen the application range of complexometric titration. The error problem is studied by means of computation. Selection of determination points and weight factors is discussed. The method has been applied to the determination of Co2+ ,Ni2+ ,Mg2+ and Zn2+ with RSD of 0. 11%-0. 32% |
