Abstract

The transport of tartaric acid through a bulk liquid membrane (BLM) was investigated. The effect of solvent type, carrier concentration, temperature, salt type and salt concentration in the feed phase on the transport efficiency of tartaric acid through the BLM was studied. 27 experiments were performed based on the Taguchi design of experiment, and the results were analyzed with Minitab 16 software. The results indicated that the maximum extraction (92.53%) was obtained under optimum conditions including methyl isobutyl ketone as a solvent, trioctylamine at a concentration of 30% (v/v) as a carrier, a temperature of 25°C and potassium nitrate at a concentration of 30% (w/v) as a salt in the feed phase. The results illustrated that the experimental error compared with the predicted value by the software was 6.69%; therefore, the Taguchi model has an acceptable capability of prediction for the tartaric acid extraction process. In addition, two irreversible first-order sequential chemical reactions were used to explain the kinetic model of the pertraction process in BLM systems.

液膜技术从水溶液中回收酒石酸：田口优化实验方法设计

摘要

研究了酒石酸通过体液膜（BLM）的运输。研究了进料相中溶剂类型，载流子浓度，温度，盐类型和盐浓度对酒石酸通过BLM传输效率的影响。基于Taguchi实验设计进行了27个实验，并使用Minitab 16软件对结果进行了分析。结果表明，在最佳条件下，以甲基异丁基酮为溶剂，浓度为30％（v / v）的三辛胺为载体，温度为25°C，温度为25°C，硝酸钾为最佳时，最大提取量为92.53％。进料阶段的盐浓度为30％（w / v）。结果表明，与软件预测值相比，实验误差为6.69％。因此，Taguchi模型对于酒石酸提取过程具有可接受的预测能力。此外，使用两个不可逆的一阶顺序化学反应来解释BLM系统中吸附过程的动力学模型。
