摘要
依据国家标准GB 1616—2003,用滴定法测定过氧化氢的质量分数,对测定过程中的各个影响因素进行分析,对检测结果的不确定度进行汇总和评定,结果表明高锰酸钾标准溶液引入的不确定度最大。
The mass fraction of hydrogen peroxide was determined by titration method in accordance with national standard GB 1616-2003.The various influence factors in the determining process were analyzed.The uncertainties of determined results were collected and evaluated.The results show that the uncertainty caused by potassium permanganate standard solution is maximum.
