络合滴定法连续测定Fe^(3+)、Zn^(2+)含量微型实验研究

A Study on Microscale Experiment of Continuous Determination of Iron Zinc Concentration by Complexometric Titration

本文利用微型滴定法测定铁、锌混合液中的Fe3+、Zn2+含量,并对微型滴定法与常量滴定法的平行测定结果进行了比较,结果无显著性差异,F检、T检结果均在允许范围内,相对标准偏差均小于1.0%,微型滴定法的精度达到常量滴定法测定水平,能满足化学分析的要求。

The concentration of Iron 、Zinc was continuous determined in the mixing solution by microtitration method and compared the results by the microburette and the routine analysis. There is no obvious difference in the results. the relative standard deviation is less than 1.0%. The t-exanine value and F-examine value are in the allowed range.And the microtitration has no significant differences compare with conventional titration and fulfills the requirements for chemical analysis.
