The removal of copper, lead and cadmium by apple residues (AR) was investigated to evaluate cation exchange capacities. The effects of solution pH, ionic strength, ligands and co-ions were studied in batch experiments. Apple residues were modified with phosphorus (V) oxychloride to improve their physico-chemical properties and greatly enhance the capacity of metal removal. Adsorption equilibria...
The use of the white-rot fungus Polyporous versicolor in Ni(II) removal as biosorbent was investigated. Kinetic and isotherm sorption experiments were conducted to evaluate the effects of pH, time, temperature, and mixing intensity. Time-course variation of Ni(II) uptake at various temperatures (20, 25, and 35 o C) and initial Ni(II) concentrations revealed that both the initial Ni(II) uptake...
