Comparison of The Sorption Kinetics of Lead(II) and Zinc(II) on Titanium Phosphate Ion-Exchanger.

The treatment of heavy metal-contaminated wastewater is an important action to reduce The negative impacts of industrial wastes on water bodies. This work focuses on The application of a low-cost titanium (IV) phosphate sorbent of TiO(OH)HPO42HO chemical composition toward lead and zinc ions depending on their concentration and The temperature of The solution. The kinetic studies showed that The values of The rate of intraparticle diffusion and The effective diffusion coefficients for Zn were considerably higher than those for Pb.
