Effect of pH and temperature on the sorption of metals ions from aqueous solution on Lonchocarpus Laxiflorus stem bark


Santuraki AH, Aliyu BA, Barminas JT

Heavy metals are most dangerous one as these are non –biodegradable and persist in environment. Human activities, such as mining operations and the discharge of industrial wastes, have resulted in accumulation of heavy metals in the environment. Removal of metals and their recovery is one of the major concerns in sewage and industrial effluent treatment. This paper attempts to present a brief summary of the role of Lonchocarpus laxiflorus Stembark (LLSB) in heavy metal removal from aqueous solutions. Encapsulated Lonchocarpus laxiflorus Stembark was evaluated for sorption ability for chromium, cadmium, nickel, lead and iron ions. It was found that stembark was able to decontaminate with good efficacy for Ni, Pb and Cr ions at pH 6, 4, 6 with 99% respectively. The maximum removal of the metals was seen at temperatures between 30 oC to 40oC. This will be advantageous for effluent treatment plant to recover important heavy metals with low cost.
