Transport of organic acids through nanofiltration membranes varies considerably under different conditions. In the present work, a Maxwell–Stefan approach coupled to the Henderson–Hasselbach equation was applied to describe succinic acid permeation through nanofiltration membranes in binary and ternary solutions. Permeate flux and solute rejection were evaluated under several test conditions, by modifying variables such as pH, gauge pressure, succinic acid concentration and presence of other solute (glucose, as a neutral solute).

用麦克斯韦-斯特凡方法通过纳滤膜进行琥珀酸转运的预测研究

在不同条件下，有机酸通过纳滤膜的传输方式差异很大。在目前的工作中，采用麦克斯韦-斯特凡方法与亨德森-哈塞尔巴赫方程相结合，以描述二元和三元溶液中琥珀酸透过纳滤膜的渗透。通过修改变量（例如pH，表压，琥珀酸浓度和其他溶质（葡萄糖，作为中性溶质）的存在），在几种测试条件下评估了渗透通量和溶质截留率。
