| 摘 要： | 本文采用甲基磺酸溶液调整pH值,以水合肼溶液还原、沉淀去除钒离子,经onguardⅡH柱过滤后进离子色谱仪测定其中Cl-、SO42-的准确含量,并实验得出检出限,Cl-为0.012mg·L-1、SO42-为0.021mg·L-1,Cl-重现性1.66%,SO42-的重现性0.90%,加标回收率Cl-为98%~105%,SO42-为101%~103%。前处理方法及检测方法是可行的。

| Abstract: | Vanadium ion was removed by hydrazine hydrate solution, the pH value of the solution was adjust- - 2- ed by methyl sulfonate, filtered using onguard Ⅱ H column, the content of C1 and SO4 were determined by ion chromatography. Detection limit of CI- was 0.012mg·L-1 and SO4 2- was 0.021mg·L-1 ,reproducibility of C1- was 1.66% 2- 2- and SO4 was 0.90%,recovery rate of C1- was 98%-105%,S04 was 101%-103%. The method of determine was acceptable. |
