【摘要】 乳化液膜选择性地分离尿素,是治疗尿毒症或缓解其症状的新型疗法,其中乳化液膜的稳定是其发展的必要条件,而表面活性剂又是影响其稳定性的重要因素。本文通过对乳液粘度的研究, 来分析亲油相表面活性剂和亲水相表面活性剂对其稳定性的影响,从而找到使乳液更稳定的表面活性剂。实验表明,油相表面活性剂选用Span-80与Tween-80复配HLB值为5时,乳液的稳定性更为理想,外水相表面活性剂选择浓度为4wt％Tween-80和0．1wt％黄原胶高分子增稠剂溶液混合,所制备的乳液更稳定。更多还原

【Abstract】 A new method, emulsion liquid membrane extracting urea, is used to cure the uremia. The one of challenges impedes the application of multiple emulsions is the unstablity of emulsion. Surfactants play an important role on its stability. The effect of lipophilic and hydrophilic surfactants on the stability is analyzed and the best condition of stability is given in the paper. It shows that emulsion liquid membrane systems are more stable under following conditions: surfactant is the mixture of Tween-80 and Span-80 whose HLB is 5 in the oil phase, surfactant is the mixture of 4wt% Tween-80 and 0.1 wt% xanthan in the outer water phase.更多还原
