摘要

Prospective hydrogel was synthesized from PVA/AAc with PC88 (2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester) organic extractant to implant for sorption and separation of yttrium (III) and zirconium (IV). PVA/AAc/PC88. to determine the physical and chemical properties of the produced hydrogel, several methods were used, including EDX and SEM, the hydrogel matrix of PVA/AAc with PC88, the weight percentages of C, O, and phosphorus (P) were determined to be 47.03%, 52.60%, and 0.38% respectively. The adsorption processes of Zr were examined with respect to a few parameters. The optimal parameters for achieving the high loading capacity of Zr and Y ions are 10.13 mg/g and 6.68 mg/g respectively. The sorption mechanism was controlled by both metals using the Langmuir isotherm ions on the surface of the PVA/AAC/PC88 adsorbent. Kinetics isotherm investigations show that the experimental results for Zr and Y were fitted with pseudo second order. The use of PVA/AAc/PC88 greatly improved the effluent’s ability to sorption and separation of Zr4+ and Y3+ from their binary mixtures.
