摘要：

In this paper we present the results related to magnetic particles synthesis (obtained by a variant of Massart method, which consists in ferric ions co-precipitation into a potassium hydroxide solution) and their stabilization with SAP 230 (consisting of a mixture of two modified polyisobutene derivatives in mineral base oil). The obtained stabilized magnetic particles were functionalized with a crown ether derivative (aminobenzo-18-crown ether) and used for liquid membranes preparation in dioxan. The colloidal magnetic particles were characterized by FT-IR spectroscopy, thermal analysis and Scanning Electron Microscopy and Na+ and K+ from different inorganic salts were separated in order to test and evaluate the liquid membrane performances.
