Title: Biosorption of Lead (II) ions from aqueous solution using Moringa oleifera pods
Abstract: The adsorption of Pb2+ onto ground Moringa oleifera pods was studied under various conditions such as, pH, contact time, adsorbent dosage, and concentration of adsorbate. The adsorption process was checked for conformity with the Freundlich and Langmuir isotherms. From the adsorption experiments conducted, it was observed that the adsorption was pH, contact time, and adsorbate concentration dependent. The adsorption process was partly dependent on adsorbent dosage. It was also discovered that the adsorption did not conform to the Freundlich and Langmuir adsorption isotherms. Maximum percent adsorption obtained after contacting the Pb2+ aqueous solution with ground Moringa pods for 180mins was 48.4% at pH 7. This study revealed that Moringa pod is not a very good biosorbent for the removal of Pb2+ from wastewater at pH.
