Defluoridation of water using as-synthesized Zn/Al/Cl anionic clay adsorbent: equilibrium and regeneration studies.
S. Mandal,S. Mayadevi +1 more
TL;DR: A two-step 1st order kinetic model was used to explain the fluoride adsorption kinetics of the as-synthesized clay and it was possible to regenerate the adsorbent with an aqueous solution of 0.01 M NaOH and the effect of regeneration on fluoride Adsorption was reported up to five regeneration cycles.

Adsorption of Cd(II) and Pb(II) onto a one step-synthesized polyampholyte: kinetics and equilibrium studies.
Guillermo Javier Copello,Guillermo Javier Copello,Luis E. Diaz,Luis E. Diaz,Viviana Campo Dall’ Orto,Viviana Campo Dall’ Orto +5 more
TL;DR: A one step-synthesized polyampholyte, bearing carboxylate and 2-methylimidazole (2MI) groups, was tested as adsorbent for the removal of Pb(II) and Cd( II) from aqueous solutions, indicating a chemical-reaction controlled process.

Sorption of uranyl ions on TiO2: Effects of pH, contact time, ionic strength, temperature and HA.
Jingjing Wang,Jingjing Wang,Bihong He,Xiaoyan Wei,Ping Li,Jianjun Liang,Shirong Qiang,Qiaohui Fan,Wangsuo Wu +8 more
TL;DR: It is very interesting to find that U(VI) sorption on TiO2 was promoted in solutions with higher back-ground electrolyte concentrations, and the reduction of U(vi) was enhanced by the exposed (101) facets and more U( VI) removal was observed.
