| 摘 要： | 本文以茜素红—S为吸附指示剂,醋酸调节pH2.6～2.9,用氯化钡标准溶液直接滴定硫酸钠含量。采用误差抵消法标定操作溶液,消除了偏低的系统误差。 快速测定法测定的相对误差为±0.55％。置信度α=95％时,可靠测定区间为49.08±0.0279。

| Abstract: | A determination is reported for the direct titration of sodium sulfate with absorbing alizarin red-S and pH2.6-2.9 adjusted by HAc solution. The negative systematic error is eliminated by using error counteration in standardizing of working solution.The relative error is 0.35%, degree of confidencea=95%and reliability range 49.08±0.02g. |
