Objective Removal of heavy metals, specially lead from wastewater Developing a porous material functionalized by graphene based materials Increase removal efficiency of heavy metals Reduce operational cost

Approach Evaluation of the performance of engineered porous material to remove heavy metals Introduce modifications on functionalization of the novel material Evaluate the performance of modified/optimized material for the removal of heavy metals and its regeneration ability Perform tests to scale up production of modified particles

Results, pH effect Series 1 Concentration = 560 ppb rpm = 150 Temperature = 25 °C C-Zeolite : solution ratio = 0.50 g : 100 ml pH = 2.2 Series 2 pH = 4 Series 3 pH = 10

Results, temperature effect Series 1 Concentration = 560 ppb rpm = 150 Temperature = 4 °C Adsorbent : solution ratio = 0.50 g : 100 ml pH = 4 Series 2 Temperature = 25 °C Series 3 Temperature = 35 °C

Results, rpm effect Series 1 Concentration = 560 ppb rpm = 50 Temperature = 25 °C Adsorbent : solution ratio = 0.50 g : 100 ml pH = 4 Series 2 rpm = 150 Series 3 rpm = 250

Conclusion pH showed a significant effect on required time to the equilibrium concentration. Temperature was not found to be a dominant factor in lead ion removal in the range of 4 – 35 ºC. Faster stirring speed showed a shorter time to equilibrium concentration.
