Abstract

Polymer inclusion membranes (PIMs) are an attractive approach to the separation of metals from an aqueous solution. This study is concerned with the use of 2-alkylimidazoles (alkyl = methyl, ethyl, propyl, butyl) as ion carriers in PIMs. It investigates the separation of copper (II), zinc (II), cobalt (II), and nickel (II) from aqueous solutions with the use of polymer inclusion membranes. PIMs are formed by casting a solution containing a carrier (extractant), a plasticizer (o-NPPE), and a base polymer such as cellulose triacetate (CTA) to form a thin, flexible, and stable film. The topics discussed include transport parameters, such as the type of carrier, initial fluxes, separation coefficients of copper in relation to other metals, as well as transport recovery of metal ions. The membrane was characterized using AFM and SEM to obtain information on its composition.

摘要

聚合物包容膜（PIMs）是从水溶液中分离金属的一种有吸引力的方法。本研究关注在PIMs中使用2-烷基咪唑（烷基 = 甲基、乙基、丙基、丁基）作为离子载体。研究了使用聚合物包容膜从水溶液中分离铜（II）、锌（II）、钴（II）和镍（II）。通过浇铸含有载体（萃取剂）、增塑剂（邻硝基苯基苯基醚，o-NPPE）和基础聚合物（如三醋酸纤维素，CTA）的溶液来形成PIMs，以形成薄的、柔性的和稳定的膜。讨论的主题包括传输参数，如载体类型、初始通量、铜相对于其他金属的分离系数，以及金属离子的传输回收率。使用原子力显微镜（AFM）和扫描电子显微镜（SEM）对膜进行表征以获取其组成信息。
