界面活性剂的混合添加对溴化锂溶液表面张力及吸收水蒸气的影响

EFFECT OF COMPOUND SURFACTANTS ON SURFACE TENSION OF LIBR AQUEOUS SOLUTION AND ITS ABSORPTION OF WATER VAPOR

本文从将两种有效添加剂混合添加的角度,来研究其对溴化锂水溶液吸收水蒸气的影响。采用静态池吸收实验测试溶液吸收水蒸气的效果。通过对正辛醇、仲辛醇、异辛醇、正己醇四种物质采用单种添加和两种混合添加的测试实验表明,混合添加后的效果与其中较好的添加剂单独添加的效果接近。采用吊板法测量溶液的表面张力。通过对添加以上混合添加剂后的溴化锂水溶液的表面张力的测试表明,混合添加后溶液的表面张力与其中较大程度降低溶液表面张力的添加剂单独添加后的表面张力接近。

Compound surfactants were added into aqueous LiBr solution to study its effect on absorption of water vapor into aqueous LiBr solution in static pool setup, n-Octanol, 2-Octanol, 2-Ethyl-1- hexanol, and 1-Hexanol were added into 60wt% LiBr solution by two ways： alone and two of them. The experiment shows that the effect of compound surfactants is near to the better one between them. Surface tension of LiBr solution with surfactants was measured by Wilhelmy plate method. The experimental result shows that the surface tension of LiBr solution with compound surfactants is near to the one who make solution tension smaller.
