Biosorption of Pb (II) and Ni (II) Ions from Aqueous Solutions Using a Biomaterial
Reena Malik [2] | Suman Lata [6] | Sushila Singhal [2]
Abstract: An increase in population initiating rapid industrialization was found to consequently increase the effluents and domestic wastewater into the aquatic ecosystem. Heavy metals are major toxicants found in industrial wastewaters; they may adversely affect the biological treatment of wastewater. Conventional methods for the removal of heavy metals from waste waters are often cost prohibitive hence; there is a need for cheap methods for effluent treatment. Azadirachta indicia leaves are converted to a fine powder for use as a biosorbent for the removal of metal ions in aqueous solution. In this work; the adsorptive interactions between Ni (II) ; Pb (II) and the powder were studied under a variety of conditions involving variations in pH; Pb (II) ; Ni (II) concentration; biosorbent amount; interaction time and temperature; all in single batch processes. The ability of Neem leaves to absorb metal ions as shown from the results can be used for the development of an efficient; clean and cheap technology for effluent treatment.
