STUDY OF THE SORPTION OF Cr(III) WITH XAD-2 RESIN IMPREGNATED WITH DI-(2,4,4 TRIMETHYLPENTYL)PHOSPHINICACID (CYANEX 272)

Removal of lanthanum and gadolinium from nitrate medium using Aliquat-336 impregnated onto Amberlite XAD-4

“…The impregnation process was carried out by dry method which is the most widely used [14]. The impregnation solution was 50 ml of 5% Aliquat-336 in benzene.…”

Sorption of Cr(VI) from aqueous solution by Amberlite XAD-7 resin impregnated with Aliquat 336

“…There are four methods available for the immobilisation of the desired extractant into the polymeric supporting structure: the dry method, wet method, modifier addition method and the dynamic column method [3][4][5][6]. All of the preparation methods have the same mechanism of the impregnation, which is proposed by Jerabek et al [7].…”

Removal of Cr(III, VI) by quaternary ammonium and quaternary phosphonium ionic liquids functionalized silica materials

“…Cr(VI) was extracted by Aliquat 336 doped in SG-3 according to an anion-exchange process [42]. [45]. We presumed that the adsorption by SG-2 and SG-5 was mainly due to the complexation of Cr(III) species with IL anions.…”
