| 摘 要： | 针对碘量法中反应试剂硫酸锰溶解缓慢、实验周期较长并伴有大量沉淀的现象,进行了氯化锰和硫酸锰对比实验,结果证明,采用氯化锰替代硫酸锰作反应试剂较好.对影响碘量法测定结果的因素进行了研究,控制适量的氯化锰和硫酸加入量.可提高碘量法的准确度.

| Abstract: | As manganese sulfate dissolving slow, determination period long with amount of deposition, the test of manganese chloride compared with manganese sulfate was carried out. The test results proved that it was better to take manganes sulfate as reaction agent. The factors affecting determination result of iodometric method were studied. The accuracy of iodometric method was raised by controlling the quantity of manganese chloride and sulfuric acid. |
