In this research work hydrolyzed poly-methyl methacrylate (HPMMA) was tested for removal of nickel and cobalt from aqueous solution. Effect of various parameters such as pH, adsorbent dose, initial metal ion concentration, contact time and temperature on adsorption of Ni (II) and Co (II) onto HPMMA was investigated. Equilibrium studies show that the adsorption follows both Langmuir and Freundlich isotherm model. Kinetic studies show that the adsorption follows pseudo-second order kinetics
