Abstract
Four composite materials with di-(2-ethylhexyl) phosphoric acid (HDEHP) as an extraction agent and PAN as a binding polymer were studied in this work. The intended use of these materials is in extraction chromatography. They were prepared by various methods and contained different amounts of HDEHP. The properties were compared by studying europium uptake from nitric acid solutions. Materials prepared by direct incorporation of extraction agent into PAN polymer during beads production and with up to 40% (w/w) of HDEHP are suitable for analytical separations. Materials with high capacity can be prepared by impregnation of ready-made PAN beads.
