甜菜碱与羧甲基纤维素钠相互作用的研究
摘要
本文通过表面张力法和粘度法研究了十四烷基甜菜碱(C
14
BE)与羧甲基纤维素钠(CMC-Na)的相互作用
并通过紫外吸收光谱法对其作用机理进行了探讨。发现在pH=2时
两者由于静电吸引作用而形成复合物
pH=7时无复合物生成
但对彼此的性质仍有影响。外加盐促进了两者间氢键的形成
使pH=7的情况下也产生了复合物。
Abstract
The interaction between the zwitterionic surfactant tetradecyl betaine(Ci4BE) and anionic polyelectrolyte sodium carboxymethyl cellulose (CMC-Na) has been investigated by measurements of surface tension viscosity and ultrovioled visible spectrosopy. As the result
it is shown that C14BE bind to CMC-Na and form complex at PH = 2 because of electrostatic force;no complex are formed at PH=7
the effect of each other are similar with electrolyte;the added NaCl impel the formation of H-binding between them
