Scavenging of Ni(II) metal ions by adsorption on PAC and babhul bark.
The removal of toxic nickel metal ions by adsorption, using powder activated charcoal (PAC) and non-conventional adsorbent modified Indian powder babhul bark (PBB), was studied at room temperature. The adsorption isotherms were obtained in a batch reactor. It is observed that, the process of uptake followed first-order adsorption rate expression and obeyed Langmuir and Freundlich models of adsorption. Effects of variations in parameters such as pH, contact time, adsorbent dose, initial Ni(II) concentration and particle size were also studied.
