Removal of Ni(II) from Aqueous Solution by Novel Lycopersicon esculentum Peel and Brassica botrytis Leaves Adsorbents

The current work reports adsorption of Ni(II) using Brassica botrytis leaves (BBL), leaves-activated carbon (BBL-AC), Lycopersicon esculentum peel (LEP) and peel-activated (LEP-AC). was tested in batch experiments by varying different parameters such as pH, initial metal ion concentration, temperature, adsorbent dosage, contact time. Thermodynamics kinetics investigations were performed for Ni removal. improved incorporation activated to the parental adsorbents. studies revealed 40 min equilibrium time Adsorption drastically declined temperature with a minimum 53% observed BBL. Similarly, solution pH also played vital role A 95% recorded case LEP-AC at 7. study concluded application active adsorbents from aqueous solution.
