dc.descriptionThis study aims at investigating the adsorption capacity of biosorbent (bambara groundnut powder; BGP, and soursop powder; SSSP) on toxic metals from synthetically prepared waste water. The adsorbents were used to examine their respective efficiency on selected metal; cadmium (Cd), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), manganese (Mn), and thallium (Tl) from the prepared contaminated water
dc.description.abstractHeavy metals have increased a greater consideration to environmental chemists due to their toxic nature. They are persistent in nature and cannot be degraded. Heavy metals can deteriorate the environment resulting in a variety of illness and disorders when entering the living tissue. This study aims at investigating the adsorption capacity of biosorbent (bambara groundnut powder; BGP, and soursop powder; SSSP) on toxic metals from synthetically prepared waste water. The adsorbents were used to examine their respective efficiency on selected metal; cadmium (Cd), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), manganese (Mn), and thallium (Tl) from the prepared contaminated water. The samples were analysed using Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). 0.2 g of (BGP) was added to 50 mL of ultra-pure water. Then separately known concentrations of the analyzed parameter were added to the solution of BGP and SSSP. The results of adsorption efficiency were: 100% each for Cd2+, Tl2+ and Pb2+; 94% for Cu2+; 81% for Zn 2+; 68% for Co2+; 64% for Mn2+; 46% Fe2+; and 07% for In2+ . The results revealed that, the metal ions were removed in the following order: Cd2+ = Tl2+ = Pb2+ ˃ Cu2+ ˃ Zn 2+ ˃ Co2+ ˃ Mn2+ ˃ Fe2+ ˃ In2+ . With the same conditions as applied in bambara ground nut powder the adsorption efficiency of the soursop seed powder were: for 100% for Cd2+; Cu2+; Tl2+and Pb2+; 83% for Zn 2+; 62% for Co2+; 49% for Fe2+; 21% for In2+; and 0% for Mn2+ with an order of (Cd2+ = Cu2+ = Tl2+ = Pb2+) ˃ Zn 2+ ˃ Co2+ ˃ Fe2+ ˃ In2+ ˃ Mn2+ . The analysis showed that both BGP and SSSP have remarkable adsorption capacity on selected metals. Suggestively, the BGP and SSSP are preferable low cost and eco-friendly alternative adsorption materials for toxic metals ions. It is therefore recommended to the society to increase the consumption of bambara ground nut and soursop as well as its seeds being an important way of getting rid of toxic chemicals from the body.
