中文名称：工业用盐酸.可溶性硫酸盐的测定.浊度法

英文名称：Hydrochloric acid for industrial use — Determination of soluble sulphates — Turbidimetric method

发布日期：1973-11

标准范围

浊度法适用于可溶性硫酸盐含量小于0.1%（m/m）的产品。其原理是将试样蒸发至干燥，并将残渣溶解在盐酸中。在明确的条件下，通过沉淀硫酸钡获得的浊度测量。也得到了IUPAC的批准。

The turbidimetric method is applicable to products containing less than 0.1 % (m/m) of soluble sulphates. The principle consists in evaporation of a test portion to dryness and solution of the residue in hydrochloric acid. Measurement of the turbidity obtained by precipitation, under well defined conditions, of barium sulphate. Has also been approved by the IUPAC.
