Sorption of phosphate from solid/liquid interface by fly ash
TL;DR: In this paper, fly ash was used to remove phosphate from aqueous solutions and the results of X-ray spectroscopy showed that the removal of phosphate from solid/liquid interface by fly ash predominantly took place by precipitation mechanism, ion exchange and weak physical interactions between the surface of sorbent and the metallic salts of phosphate.

Kinetic Studies on Fluoride Removal by Calcined Layered Double Hydroxides
TL;DR: In this paper, the effects of pH, initial fluoride concentration, CLDH quantity, and temperature on the kinetic of fluoride removal have been tested in detail, and the results of four kinetic models fitted to the experimental data show that the pseudo-second-order kinetic model gave a better description for the uptake process.
