Extracting microamounts of Sc 3+ ,Y 3+ ,Nd 3+ and Er 3+ by loaded foamed polymer with synergistic reagent PMBP and TTA

Abstract:	The best experiment conditions (such as the concentration of extraction agent, temperature, acidity) were studied, when microamounts of rare earth Sc 3+ , Y 3+ , Nd 3+ and Er 3+ were extracted by loaded foamed polyurethane (polyether type) with synergistic reagent PMBP and TTA. The performance of extraction (percentage extraction, ratio of separation, extraction capacity) was investigated. It was proved that this is a practical method of extraction.

Keywords:	extraction scandium yttrium neodymium erbium synergistic reagent foamed polyurethane
