Bagasse pith was tested for its ability to remove cadmium and lead ions from aqueous solutions under two modes of operation, i.e. in batch systems and continuous flow systems. Time dependency experiments showed a very rapid adsorption of these cations by bagasse pith. Thus, 62% of cadmium ions and 84% of lead ions were taken up by the bagasse pith at pH 6 and ca. 99% of each cation was recovered by treatment of the pith with 0.1 M HCl. The breakthrough capacity, Q0.5, the number of theoretical plates and the theoretical plate height were calculated. The capacity of bagasse pith was found to be 6.2 and 8.5 mequiv./g for cadmium and lead ions, respectively. The feasibility of using bagasse pith for cadmium and lead ion removal from wastewater streams was addressed.

Abstract The present work focused on the utilization of three local wastes i.e., rambutan (nephelium lappaceum), langsat (lansium parasiticum) and mango (mangifera indica) wastes as organic substrates in benthic microbial fuel cell (BMFC) to reduce the cadmium and lead concentrations from synthetic wastewater. Out of the three wastes, the mango waste promoted a maximum current density (87.71 mA/m2) along with 78 % and 80 % removal efficiencies for Cd2+ and Pb2+, respectively. The bacterial identification proved that Klebsiella pneumoniae, Enterobacter, and Citrobacter were responsible for metals removals and energy generation. Lastly, the BMFC mechanism, challenges and future recommendations are enclosed.
