Date nuts dust was used to remove Ni(II) from aqueous solutions and industrial wastewaters by the adsorption. Batch mode adsorption experiments are carried out to assess kinetic and equilibrium parameters. They allow initial adsorption coefficient, adsorption rate constant and maximum adsorption capacities are to be computed. Removal of mg/g increase with increase of metal concentration and contact time. The adsorption data that have been analyzed and fitted to both Langumuir and Freundlich classical adsorption isotherm models. The adsorption capacity (Qo) calculated from Langumuir isotherm was 1.71mg Ni(II)/g of Begasse at initial pH of 5.0 at 27+2oC for particle size 0.430 mm. Increase in pH from 2-10 increased percent removal of metal upto 5.0 later onwords 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 was on the Date nuts dust surface quantitative recovery of Ni(II) is possible by HCl.
