| 摘 要： | 研究了铬天青S分光光度法测定铝时,样品消化液中残留高氯酸根的干扰及其消除方法,用阴离子交换树脂将样品消化液中残留的高氯酸根交换去除。结果表明,样品经过阴离子交换树脂柱后,高氯酸根基本去除,不再产生混浊,且铝的回收率达90%。该法简便可行,提高了铝测定的准确度。

| Abstract: | To study the interference and elimination method of residual ClO4- in determination of aluminum by chromium azure S spectrophotometry.Anion-exchange resins chromatography was used to remove ClO4- in digested solution of the sample.The results showed that ClO4- was eliminated when the solution passed through the column and no turbidity was found.The recovery rate of aluminum was 90%.It conclded the method was simple and effective.The accuracy of the determination was improved. |
