La (III) Separation by Tri Octyl Phosphine Oxide (Cyanex 921) Based on Amberlite Xad-4 Chelating Resin

Abstract The novel core–shell type polymeric supports with accessible phosphorus groups were synthesised in the search for new reactive materials designed synthesis of functional resins. Amberlite XAD-4 adsorbent was impregnated tri octyl phosphine oxides (Cyanex 921), which then polymerized polymer carrier structure. syntheses evaluated by capturing FT-IR spectra, SEM micrographs, and analysing sorption process. Batch studies conducted to study influence some factors like pH, contact time, metal ions concentration, temperature on efficiency La (III) ions. results showed that optimum conditions at pH equal 0.5 an equilibrium time 30 min. According data analysis, pseudo-second-order Langmuir models better fitted than other estimated models. capacity into resin as martial 54.25 mg g ?1 . revealed used has been successfully a promising material elimination recovery from aqueous solutions. exhibits high chemical stability, reusability fast equilibration. Further, above procedure employed application real sample.
