Abstract

The global production of electronic scrap is an environmental problem. An important part of this waste is precious metals. To recover them, several separation methods are used, such as extraction with encapsulated extractants, being necessary to manufacture stable emulsions. This paper presents results of the fabrication of materials with the ionic liquid (IL) Cyphos IL 101 (trihexyl(tetradecyl)phosphonium chloride) encapsulated with calcium alginate by reverse gelling. Emulsions of LI, carboxymethylcellulose (CMC) and gum arabic as emulsifier were used. The materials stability and their performance in the Au(III) extraction were studied as a function of the fabrication time. The obtained results are compared with them previously obtained with similar materials without GA. Emulsions and microcapsules with GA show a higer stability. Increasing the fabrication time, both materials show a decrease of the extraction capacity and speed, but these variations were lower for the microcapsules with GA.
