Abstract

The toxicity and carcinogenic effect of many drugs including antibiotics have brought up an environmental worry in the recent years. The current study examined a green emulsion liquid membrane (ELM) as an environmentally-friendly method for extracting Vancomycin antibiotic from its aqueous solutions. The main value of the idea is to reduce environmental risks of employing common unsafe organic solvents applied as diluent in the ELM process. For this purpose, the raw sunflower oil was employed to prepare ELM. An organic phase including the sunflower oil (diluents), Span 80 (emulsifier) and bis(2-ethylhexyl)phosphoric acid (D2EHPA) carrier was mixed with internal aqueous phase (stripping phase) containing NaOH. The results confirmed that almost 100% of Vancomycin was successfully extracted at the optimum conditions affecting parameters for preparing the membrane. The extraction percentage and emulsion stability was acceptable for the feeds with wide range of pH from 5-9 and NaCl concentration from 0-5 g/L. Also, a recovery percent of around 70% was achieved for the captured Vancomycin when the emulsion was broken.

葵花油绿色乳液液膜法从水中提取万古霉素类抗生素

近年来，包括抗生素在内的许多药物的毒性和致癌作用引起了人们对环境的担忧。本研究考察了绿色乳液液膜（ELM）作为一种从其水溶液中提取万古霉素抗生素的环保方法。该想法的主要价值是降低在ELM工艺中使用常见的不安全有机溶剂作为稀释剂的环境风险。为此，使用生葵花油来制备ELM。将包括葵花油（稀释剂）、Span 80（乳化剂）和双（2-乙基己基）磷酸（D2EHPA）载体的有机相与含有NaOH的内部水相（汽提相）混合。结果证实，在影响膜制备参数的最佳条件下，几乎100%的万古霉素被成功提取。对于pH范围为5-9和NaCl浓度为0-5g/L的宽饲料，提取率和乳液稳定性是可接受的。此外，当乳液破裂时，捕获的万古霉素的回收率达到约70%。

期刊介绍： The Journal of Membrane Science and Research (JMSR) is an Open Access journal with Free of Charge publication policy, which provides a focal point for academic and industrial chemical and polymer engineers, chemists, materials scientists, and membranologists working on both membranes and membrane processes, particularly for four major sectors, including Energy, Water, Environment and Food. The journal publishes original research and reviews on membranes (organic, inorganic, liquid and etc.) and membrane processes (MF, UF, NF, RO, ED, Dialysis, MD, PV, CDI, FO, GP, VP and etc.), membrane formation/structure/performance, fouling, module/process design, and processes/applications in various areas. Primary emphasis is on structure, function, and performance of essentially non-biological membranes.
