本欧洲标准规定了阴离子表面活性剂中无机硫酸盐含量的测定方法。它可以应用于α-烯烃磺酸盐和n-烯烃磺酸盐，醇硫酸盐，醇醚硫酸盐，烷基苯磺酸盐和其他烷基磺酸盐。该方法也用于测定烷基苯磺酸盐或其酸形式的其它烷基磺酸盐中的无机硫酸盐。该方法也适用于深色样品。 注意硫酸盐可以作为硫酸，这种酸的离子盐或这些的混合物存在

This European Standard specifies a method for the determination of the content of inorganic sulphate in anionic surface active agents. It can be applied to a-olefin sulphonates and n-olefin sulphonates, alcohol sulphates, alcohol ether sulphates, alkyl benzene sulphonates and other alkyl sulphonates. This method is used also for the determination of inorganic sulphate in alkyl benzene sulphonates or other alkyl sulphonates in their acid form. This method also applies to deep-coloured samples. NOTE Sulphate can be present as sulphuric acid, ionic salts of this acid or mixture of these.
