ISO 731-5:1977 工业用甲酸 试验方法 第5部分:无机硫酸盐目测限度试验

The principle consists in a comparison of the turbidity, obtained by the addition of barium chloride to a solution prepared from a test portion in the presence of hydrochloric acid, with that similarly obtained from a standard sulphate solution. The method is a applicable to products having inorganic sulphates contents, expressed as sulphate (SO42-), in the range 0, 001 to 0, 1 % (m/m).
