Abstract This work highlights extraction and removal of Lignosulfonate using sunflower oil-Tri-n-octylamine (TOA) system in bulk liquid membrane transport. Maximum extraction and recovery percentages of 92.4% and 75.2% were achieved. Optimum manifold operating conditions were: 4 vol.% TOA, 2 ± 0.1 feed phase pH, 300 rpm stirring speed, at 40 °C with 0.2 (M) Na2SO4 solution. 1:2 (organic/aqueous) and 1:1 (aqueous/aqueous) phase ratios produced best results. Extraction (36.85 kJ/mol) was found to be intermediate controlled and stripping (54.79 kJ/mol) was chemical reaction controlled. Kinetic estimation of data with higher rate constants for stripping vis-a-vis extraction showed latter to be rate determining.

使用葵花籽油作为液体膜运输中的绿色溶剂高效提取和回收木质素磺酸盐：平衡和动力学研究

摘要 这项工作重点介绍了使用葵花籽油-三正辛胺 (TOA) 系统在散装液膜运输中提取和去除木质素磺酸盐。达到了 92.4% 和 75.2% 的最大提取率和回收率。最佳歧管操作条件为：4 vol.% TOA，2 ± 0.1 进料相 pH，300 rpm 搅拌速度，在 40 °C 下使用 0.2 (M) Na2SO4 溶液。1:2（有机/水相）和 1:1（水/水）相比产生最佳结果。发现萃取 (36.85 kJ/mol) 受中间控制，而汽提 (54.79 kJ/mol) 受化学反应控制。具有较高速率常数的数据的动力学估计用于剥离相对提取表明后者是速率决定性的。
