标准摘要
[中文适用范围]： 该测定是在由水相和氯仿相组成的相中，在硫酸钠存在下，在由以下物质的混合物组成的指示剂存在下，通过用标准体积阳离子活性溶液（苄索氯铵）滴定来进行的。 阳离子染料（溴化二胺）和阴离子染料（酸性蓝 1）。 [外文原描述]： The determination is carried out in a consisting of an aqueous phase and a chloroform phase, in the presence of sodium sulfate, by titration against a standard volumetric cationic-active solution (benzethonium chloride), in the presence of an indicator consisting of a mixture of a cationic dye (dimidium bromide) and an anionic dye (acid blue 1).
