摘要
通过改变加酸顺序和实验器皿,对测定矿石中锰含量的高氯酸氧化法进行改进,并用改进的方法测定国家标准样品。研究表明,测定结果与标准值一致,改进后的方法降低了检测成本,提高了检测效率,可以满足日常的分析需要。
The perchloric acid oxidation method used in determination of the manganese content in ore is improved by altering the sequence of acidulation and types of labware.The improved method was applied to determine the manganese content in geological standard reference materials.The test results was consistent with standard value.The improved method reduces the costs of test,enhances the efficiency of test and meets the daily analysis requirment.
