氯气干燥用废硫酸质量分数测定方法的改进

摘要

改进氯气干燥所用硫酸质量分数的测定方法，在很大程度上解决了废硫酸中游离氯对分析检验结果的干扰，从而提高了分析检验结果的准确度。%The interference of free chlorine in the results of determining the mass fraction of waste sulfuric acid used for chlorine gas drying was overcome to a large extent by improving the determination method.Thus, the accuracy of determination results was increased .
