Abstract

A GO-COOH/Ce complex was introduced into a phenolphthalide polythersulfone (PES-C) matrix to prepare a PES-C/(GO-COOH/Ce) blended membrane by nonsolvent-induced phase transformation (NIPS). FT-IR and EDS analysis confirmed that the GO-COOH/Ce complex was successfully incorporated into the PES-C matrix. SEM showed that the blended membrane possessed an asymmetric structure with finger-like pores. The best comprehensive performance was obtained for a PES-C/(GO-COOH/Ce) blended membrane prepared using 0.1 wt.% of the GO-COOH/Ce complex in the casting liquid. The specific results for the blended membrane were as follows: the fluxes of pure water and 0.1 g/L lead nitrate solution were 272 L/m2·h and 214 L/m2·h, respectively; the rejection of bovine serum albumin (BSA) was 99.4%; the rejection of lead ions was 96.2%; the moisture content was 10.9%; the contact angle was 67.1°; the Young's modulus was 35.7 MPa; and the flux recovery ratio was 1.5 times higher than that of the pure PES-C membrane. The antibacterial-zone diameters of the PES-C/(GO-COOH/Ce) blended membrane used against Escherichia coli and Staphylococcus aureus were 2.50 cm and 2.88 cm, respectively. A catalytic cleaning test showed a flux recovery ratio of 63% after washing the PES-C/(GO-COOH/Ce) blended membrane with a 0.2 g/L acetic acid solution for 0.5 h.

新型PES-C/（GO-COOH/Ce）复合膜处理重金属离子废水

将GO-COOH/Ce配合物引入到酚酞聚醚砜(PES-C)基体中，采用非溶剂诱导相变(NIPS)法制备了PES-C/(GO-COOH/Ce)共混膜。FT-IR和EDS分析证实，GO-COOH/Ce配合物成功地结合到PES-C基质中。扫描电镜显示，混合膜具有不对称的指状孔隙结构。在浇注液中加入0.1 wt.%的GO-COOH/Ce络合物，制备的PES-C/(GO-COOH/Ce)共混膜综合性能最佳。结果表明:纯水和0.1 g/L硝酸铅溶液的通量分别为272 L/m2·h和214 L/m2·h;牛血清白蛋白(BSA)排异率为99.4%;铅离子的去除率为96.2%;含水率为10.9%;接触角为67.1°;杨氏模量为35.7 MPa;通量回收率是纯PES-C膜的1.5倍。PES-C/(GO-COOH/Ce)混合膜对大肠杆菌和金黄色葡萄球菌的抑菌带直径分别为2.50 cm和2.88 cm。催化清洗实验表明，用0.2 g/L的醋酸溶液洗涤PES-C/(GO-COOH/Ce)共混膜0.5 h，通量回收率为63%。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
