摘要
正十六烷基三甲基溴化铵[C_(16)H_(33)N(CH_3)_3Br]是一种阳离子表面活性剂(用CTAB示),它具有很强的杀菌能力,被广泛应用于消毒、灭菌等。由于它易吸附于一般固体表面,因而常用作矿物浮选剂和直接染料固着剂,作为一种表面活性剂能形成胶束是它的一个重要特性。本文利用环法对CTAB的临界胶束浓度(用cmc示)进行了研究,并讨论了温度及不同添加物对CTAB的cmc影响,利用表面化学原理对某些现象作了讨论。
Cetyltrimethylaramoniura bromide (CTAB) is kind of cation surfactant, It has itrong sterilize, and is widely used as disinfectant and germicide, It is easily absorbed on the surface of general solid. So it is also a mineral flotation agent and fixing agent of direct . dyes. As a surfactant micellzation is an important characteristic of CTAB. The ring method has been used to study the critical micelle concenlration (cmc) of CTAB, The effects of different temperature and additive on the cmc of CTAB and some phenomena with principles of surface chemistry have also been discussed.
