  Sorption of Pb2+, Cd2+ and Cr2+ in aqueous solution using immobilized Cissus populnea stem bark powder as a bio-sorbent was studied. The maximum sorption capacity of ICPSB on Pb2+, Co2+ and Cr2+ are 94.20%, 88.19% and 78.97% respectively. Effect of concentration on the sorption capacity of ICPSB shows that sorption capacity increase with increase in concentration while effect of ionic strength curve shows that sorption capacity decrease with increase in ionic strength. Effect of time on sorption capacity of ICPSB was observed between 1-24 hours, it was observed that Pb2+ recorded the maximum sorption compared with Co2+ and Cr2+. Effect of pH was studied at pH range of 1.0-8.0. Optimal sorption was recorded at pH 8.0 for Pb2+. The result of this research has added to the use of a cheaper bio-sorbent i.e. immobilised Cissus populnea stem bark (ICPSB) for sorption of Pb2+, Co2+ and Cr2+... Read More»
