Nickel is a naturally occurring heavy metal that is commonly used in industrial processes. The long time exposure of Nickel (II) causes significant adverse health effects to humans. Biosorption is one of the major techniques for the removal of heavy metals from various sources and it is a cost-effective means for the treatment of metal-bearing water. In the present study, biosorption was conducted under different conditions such as varying pH (2, 4, 6, 8, 10), shaking velocity (100, 150, 200 rpm), concentration (100, 150, 200 mgL-1) and biosorption dosage (0.75, 1.25, 1.75, 2.25, 2.75 g) for the biosorption of Nickel (II) by Allium cepa skin.
