表面活性剂改性皂土吸附结晶紫的研究
|
摘要
以双十六烷基二甲基溴化铵和双十烷基二甲基溴化铵的改性皂土作为吸附剂,研究不同pH值、吸附温度和初始质量浓度的改性有机皂土对结晶紫的固-液吸附的影响。结果表明:溶液的pH值对平衡吸附量的影响较小,两种吸附剂对结晶紫的吸附作用是一个熵增自发的吸热过程,吸附过程更符合单分子层吸附的Langmuir等温吸附模型以及拟二级动力学的模型。
The effects of pH values, temperature conditions and initial mass concentration of the crystal violet were studied using bis-hexadecyl dimethyl ammonium bromide and diadecyl dimethyl ammonium bromide modified bentonite as adsorbents. The results showed that the pH value of the solution has little effect on the equilibrium adsorption capacity of the two adsorbents. The adsorption of crystal violet on the organic bentonite is a spontaneous and endothermic process, and the adsorption process accord with the Langmuir isothermal adsorption model of monomolecular layer adsorption model and pseudo-two-order kinetics.
