The present study is about the application of Alamine 336 as an ion carrier in PIMs. The separation of copper (II), cobalt (II), nickel (II) and cadmium (II) from aqueous solutions with polymer inclusion membranes was investigated. PIMs are formed by casting a solution containing a carrier (extractant), a plasticizer and a base polymer, such as cellulose tri-acetate (CTA) or poly(vinyl chloride) (PVC), to form a thin, flexible and stable film. Several important transport parameters such as the type and amount of the plasticizer, the type of the stripping solution, the thickness of the membrane, the pH of the acid in the donor phase and the concentration of the base in the acceptor phase are discussed. The membrane was characterized to obtain information regarding its composition using AFM, FT-IR and SEMMembrane, ki vsebujejo polimere (PIM), so zanimive za ločenje kovin iz vodnih raztopin. Prikazana je študija uporabe Alamina 336 kot nosilca ionov v PIM. Preiskovano je bilo ločenje bakra (II), kobalta (II), niklja (II) in kadmija (II) iz vodnih raztopin z membrano s polimeri. PIM je bila izdelana z ulivanjem raztopine z nosilcem (ekstraktantom), z mehčalcem in osnovo iz polimera, kot je celuloza-tri-acetat (CTA) ali polivinil klorid (PVC), da je nastala tanka, gibljiva plast. Razloženih je več pomembnih transportnih parametrov, kot so delež mehčalca, vrsta raztopine za snemanje, debelina membrane, pH kisline v donorski fazi in koncentracija baze v aceptorski fazi. Izvršene so bile preiskave z AFM, FT-IR in SEM, da bi dobili podatke o sestavi membraneTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
