2. 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

3. 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

5. 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

6. 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

7. 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.
