Main Article Content
This research aims to study the adsorption of copper from copper-citrate solution generated from bioleaching electronic waste by chelating resin Bis (2-pyridylmethyl) amine functional group (Dowex m4195 H-form). All experiments have been studies using batch adsorption techniques. The influence of pH, temperature and contact time of adsorption was also investigated. Results indicated obviously that the adsorption of copper depends on the pH level of the solution. Nonlinear regression analyses found that pseudo-second model accurately described process kinetic. The value of the rate constant (k2) increased with increasing of pH and temperature with the maximum uptake of copper about 71.87 mg g-1 at pH 2-2.5 by using Dowex m4195 rasin. Moreover, batch-desorption demonstrated that 2 M sulfuric acid could be desorption copper effectively better than Hydrochloric acid with the 52% (31.25 mg g-1). The spent sorbent efficiency. The intrinsic Dowex m4195 rasin befit for recovery copper from bioleaching electronic waste.
