Adsorption study of arsenic removal by novel hybrid copper impregnated tufa adsorbents in a batch system
Performance of a novel adsorbent, copper impregnated natural mineral tufa (T–Cu),
applicable for efficient arsenic removal is presented in this study. Testing of adsorbent
properties encompassed material characterization and equilibrium study in a batch system.
Copper modification contributed to increased adsorption capacities, that is, from 4.65 to
67.83 mg g− 1 for As (III), and from 6.84 to 104.62 mg g− 1 for As (V), comparing to
unmodified tufa. The obtained thermodynamic data indicated higher feasibility and …
