《GB/T 11276-1989阳离子表面活性剂(氢氯化物和氢溴化物)临界胶束浓度的测定 反离子活度测量法》由606(中国石油和化学工业联合会)归口,主管部门为中国石油和化学工业联合会。
本标准规定了用多晶膜离子选择电极、参比电极组成的电池测量阳离子表面活性剂在蒸馏水或其他水体系反离子活度,从而求得其临界胶束浓度的方法。本标准适用于溶解于水和具有克拉夫特温度低于60℃的经提纯或未提纯的阳离子表面活性剂。
Scope
This standard specifies the use of a battery composed of a polycrystalline membrane ion selective electrode and a reference electrode to measure the counter ion activity of cationic surfactants (hydrochloride and hydrobromide) in distilled water or other water systems, so as to obtain their critical micelles method of concentration. This standard applies to purified or unpurified cationic surfactants (hydrochlorides and hydrobromides) that are soluble in water and have a Krafft temperature below 60°C.
