摘要
用四羟基醌——硫酸钡滴定法测饮水中硫酸盐,与国家标准方法对比,测得的结果无显著性差异。变异系数小于5％,加标回收串为97.4％～103.5％。读方法用于饮水中硫酸盐的分析,操作简便,无需特殊仪器,准确可靠,可推广使用,特别适合县级实验室开展上作。
A method is given for determinating sulfate of the drinking water by tetrahydroxyquinon-barium sulfate titration.The determinated result has no significant difference compared with national standard testing method. The coefficient of variation is below 5% and the recovery is 97. 4%~103. 5%.This method is applied to the analysis of sulfate of the drinking water. It proved to be accurate and convenient to be used in the laboratory in the county.
