摘要
使用改进的实验方法和计算公式,以离子选择电极法测定SDS胶束体系中反离子缔合度β,所得结果与有关NMR自扩散系数法测定结果一致,外加盐对反离子缔合度β值及其测定没有影响。
The results from the measurements of counterion association degree by the ion-selective electrode with improved in expriment and equation in SDS micelle systems are identical with that by NMR.The study also shows that the salt concentration have no effects on the counterion association degree in micelle system and the measurements of counterion association degree.
