International Journal of Environmental Engineering (IJEE), Vol. 2, No. 4, 2010

Abstract: The adsorption of Ni (II) from nickel electro plating rinse water has been attempted. Indion 225 and Dueolite C 20 cation-exchange resins through batch and column mode for the recovery of Ni (II), which showed a remarkable increase in sorption capacity. On the basis of isotherm analysis, more efficient adsorbent is chosen for column mode adsorption studies. The continuous-flow study was to investigate the effect of various process variables, like bed height, hydraulic loading rate on breakthrough and adsorption capacity. An attempt has also been made the data using Bohart–Adams approach to design the adsorption system.
