标准范围

在由水相和氯仿相组成的溶液中,在硫酸钠存在下,通过对标准体积阳离子活性溶液(氯化苯乙铵)进行滴定,在由阳离子染料(溴化二亚胺)和阴离子染料(酸性蓝1)的混合物组成的指示剂存在下进行测定。

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).
