Abstract :
Borasus flebellifer ferra drupe (BFFD) dust was used to remove Ni(II) from aqueous solutions and industrial wastes by the adsorption. Batch mode adsorption experiments are carried out to assess kinetic and equiliium parameters. They allow initial adsorption coefficient, adsorption rate constant and maximum adsorption capacities are to be computed. Removal of mg/g increases with increase of metal concentration and contact time. The adsorption data have been analyzed and fitted to both Langmuir and Freundlich classical adsorption isotherm models. The adsorption capacity (Qo) calculated from Langmuir isotherm was 2.05 mg Ni(II)/g of BFFD at initial pH of 5.0 at 27?2oC for particle size 0.430mm. Increase in pH from 2–10 increased percent removal of metal upto 5 latter on wards removal of metal is negligible, coupled with regeneration study of Ni(II) by HCl, allowed us to propose an adsorption mechanism by ion–exchange between metal ion and H+ ions on the BFFD surface quantitative recovery of Ni(II) is possible by HCl.
