Abstract

This work presents the removal of arsenic(V) ions from synthetic produced water via hollow fiber supported liquid membrane (HFSLM). The liquid membrane contains N-methyl-N,N,N-trioctylammoniumchloride (Aliquat 336, extractant) and corn oil (solvent). Four stripping solutions i.e. NaOH, HCl, thiourea, and HCl + thiourea are investigated. Optimum conditions found proved to be pH 12 of feed solution, 0.54 M Aliquat 336 in corn oil, and flow rates of 100 mL min-1 for both feed and stripping solution, via response surface methodology (RSM) combined with face centered central composite design (FCCD). Percentages of arsenic extraction and stripping reached 99 % and 100 %, respectively, at 323.2 K. Kinetic studies, thermodynamic parameters, extraction and stripping mechanisms, and mass transfer resistance are analyzed. To enhance liquid membrane stability, the properties of corn oil and the optimal pH demonstrate water resistance capability. New mathematical models, using an integrating factor method, developed to predict the mass transfer of arsenic ions during extraction and stripping, are seen to fit in well with the experimental data and reveal deviations of 6.2 % and 2.8 %, respectively.

利用HFSLM对绿色液膜（Aliquat336 +玉米油）有效去除和回收As(V)进行了数学建模和优化

本文介绍了利用中空纤维支撑液膜（HFSLM）去除合成采出水中的砷离子。液膜含有N-甲基-N、N、N-三辛基氯化铵（Aliquat 336，萃取剂）和玉米油（溶剂）。研究了NaOH、HCl、硫脲和HCl +硫脲四种溶出溶液。通过响应面法（RSM）结合面心中心复合设计（FCCD），发现最佳条件为饲料溶液pH为12，玉米油中Aliquat 336为0.54 M，饲料和脱提液的流速为100 mL min-1。在323.2 K下，砷的萃取率和溶出率分别达到99%和100%。动力学研究、热力学参数、萃取和剥离机理以及传质阻力进行了分析。为了提高液膜稳定性，玉米油的性质和最佳pH值表现出抗水能力。采用积分因子法建立了新的数学模型，用于预测砷离子在提取和剥离过程中的传质，与实验数据吻合良好，偏差分别为6.2%和2.8%。
