Pb2+ removal by using activated coconut waste modified with different metal oxide nanoparticles / Norhusna Mohamad Nor and Jama’atul Hasanah Md Wazir

Lead (Pb) is normally found in wastewater discharge from industrial manufacturing. The removal of lead ions (Pb2+) is important to comply with the allowable wastewater discharge limit. To improve the removal of Pb2+ in wastewater, this study focused on investigating the effect of different metal oxi...
