Adsorption of nickel ions from aqueous solution by exhausted coffee grounds

The possible use of exhausted coffee grounds as an adsorbent for the removal of nickel (II) ions from aqueous solution was investigated as a potential low-cost an alternative treatment to treat wastewater containing nickel (II) and other heavy metal ions. The effects of relevant parameters including...
