摘要
为提高燃烧碘量法测硫滴定终点的判断准确性,避免由于肉眼观察产生的误差,采用比色法定量判定颜色的深浅程度,并通过实验数据分析确定适宜的测定条件,基准色吸光度值为0 2-0 3,吸收液基准色调好后应放置10-20min。
In order to improve the accuracy to evaluate the end point of sulfur titration by burning iodimetry,and avoid the toberance caused by visual observation the colorimetry was used to evaluate the density of color by quantity.The suitable evaluation conditions were analyzed and determined with experimental data--absorption value of base color is 02-03,and the base color of absorption liquid should be settled for 10-20 minutes after mixture.
