Removal of Cd(II) ions From Aqueous Solution using Nano sized Moringa Oleifera
This research aims to study the effect of nano sized _Moringa oleifera_ on adsorption of Cd2+ ions from aqueous solution. The investigated biosorbent was characterized by FTIR, SEM, TEM, XRD and EDS techniques. The influence of pH, temperature, adsorbent dosage, contact time, metal ion concentration and chemical treatment of biomass were investigated. The maximum capacity (qm) of Cd2+ ions biosorption ...
