Abstract

Hydroxyapatite and β-tricalcium phosphate as a porous composites were prepared by a sol-gel process. We got a solid powder form composites as small particles. Mixed powder by ultrasonically dispersed throughout the aqueous solution containing an optimum amount of Ring-opening- polymerization was used for the preparation of a poly(d,l-lactide-co-glycolide Acid hydrogel polymer -functionalized polymer to appropriate for solid-phase extraction of metal ions from aqueous solutions. Resins were prepared by the copolymerization of the efficacious monomer. After the sol-gel process. Then, the nano-compound materials were used as absorbents to remove zinc ions from the aqueous solutions. The adsorption behaviors of nano-composites had been studied also. Experimental results revealed that the n-HAP/PLGA-β-TCP had greater adsorption capacity than nHAP/ β-TCP , and poly(d,l-lactide-co-glycolide Acid played vital role for the adsorption of Zinc ions. Moreover, the adsorption isotherms were applied by the two models Langmuir and Freundlich , The adsorption of metal ions can be explained the effect of composites recycle on the adsorption process on the cations by the Langmuir and Freundlich models effect and show the fitting of Zn(II) adsorption of correlation coefficient the Freundlich model is the best than Langmuir model
