| The paper makes an attempt to create a polymer sorbent competitive for the commercial Lewatit OC-1026. Therefore the commercial Amberlite XAD-7 was impregnated with the D2EHPA acid. After preparation of both exchangers, their sorption properties towards In(III) and Ga(III) ions were studied [1]. It proved that for pH = 2.17 Amberlite XAD-7 impregnated with D2EHPA acid is characterized by larger sorption capacities than those of commercial Lewatit OC-1026 towards both Ga(III) and In(III) ions. Lewatit OC-1026 as well as the prepared impregnant (XAD-7 + D2EHPA) were examined by means of Raman spectroscopic, FT-IR photoacoustic spectroscopy and FT-IR methods. |
