Toxicity has occurred in workers exposed to nickel dust or nickel carbonyl formed in refining. Increased risk of nasal and lung cancers was linked to occupational nickel exposure before current workplace safety standards were set. Activated carbon with nano holes used for removing contaminants in environment. The purpose of this work is preparation a new nano-absorber, GZ-BAKI-TAC-Ni-88, for the adsorption of water soluble Nickel ions in polluted water. The adsorption capacity and the kinetic of maximum percent by metal concentrations in 50 and 100 and 150 ppm were studied. The amount of Nickel uptake was 52.0, 95.0 and 141.6, respectively. The maximum adsorption of Nickel achieved (q) 141.6 in 1200 minutes with 150ppm primary concentration of Nickel. Results indicate that the GZ-BAKI-TAC-Ni-88 with good absorbing water solution of Nickel separation and increasing Carbon Nano-holes and Active absorption of Sodium Alginate increased Nickel. According H-equation, the maximum adsorption of Nickel ions are calculated, the mg amount per gram absorber (TAC) is 55(mg/g) or 55000 ppm respectively. In comparison with published paper is highest capacity Ni, 17.21 mg/g or 17210ppm respectively. Kinetic adsorption of Ni indicated amount of 61.234%Ni occurs on 1320 min for Nickel. SEM images of this adsorber indicate the existence of micro and meso hole and occupation by Ni ions.
