Contaminant ions adsorption properties. The time dependence of adsorption capacity of arsenic (A), fluoride (B) and nitrate (C) by PG at three different concentrations of 130 mg/l, 150 mg/l and 200 mg/l. (D) Recyclability of PG for the removal of arsenic, fluoride and nitrate. (E) Pseudo-first and (f) -second order models was found to fit the adsorption of arsenic (100 mg/l) on PG.
