Abstract

Humans consume metallic elements through both food and water. Heavy metals like cadmium, mercury, lead and arsenic which are in the list of 10 chemicals of major public concern in the World's Health Organization. Nickel is a natural element obtained from the core of the Earth. It has silver white color with a shining base and golden tint in it. Nickel is extracted from two ores - magmatic sulfides and laterites. The presence of Nickel ions in drinking water in concentrations that exceeds the permissible limit of 0.02 mg⁄L may cause adverse health effects such as anemia, diarrhea, encephalopathy, hepatitis, lung and kidney damage, gastrointestinal distress, pulmonary fibrosis, renal edema, skin dermatitis, and central nervous system days function. The various characterization tests are as follows: pH, Decolorizing powder, Hardness, Iodine adsorption value, Particle size. Characterization Test Results for pH is 8.21, hardness no is 0.366, Decolorizing powder is 570, Iodine adsorption value is 1165 and particle size are 600 µ, 250 µ, 125 µ, 75 µ. The aim of the project is to study the removal of nickel from aqueous solution using bamboo activated carbon at different dosage (0.5 g⁄l, 1.0 g⁄l, 1.5 g⁄l, 2.0 g⁄l), different agitation speed (25 rpm, 50rpm, 75 rpm, 100 rpm), different particle size (2.36 mm, 1.18 mm, 600 microns, 300 microns), and different concentration (25%, 50%, 75%, 100%) using jar test apparatus at the duration of 120 min. For the equilibrium concentration, Langmuir and Freundlich models are plotted to analyse which model is fitted with the experimental data. Removal of nickel from aqueous solution using bamboo activated carbon at dosage of 1.5 g⁄l, agitation speed of 25 rpm, particle size of 300 microns and concent6ration of 25% is 98.8%. For the equilibrium concentration, Freundlich model is best fitted. The FT-IR analysis shows the presence of functional groups like alcohols, alkanes or alkyl, aromatic ring compounds.
