|a Adsorption of heavy toxic metals by agricultural solid wastes has emerged as an alternative method of removal. Biosorption of Pb (II) has been studied by rice husk powder and maize stem powder at optimum pH, biosorbent doses, and contact time. Maximum percentage removal has been recorded at pH 7.With an increased dose of maize stem powder and rice husk powder, enhanced biosorption took place. A comparative study of biosorption by maize stem and rice husk powder revealed that maize stem powder had been found more suitable than rice husk powder at pH 7. Furthermore, the effect of contact time on the adsorption of Pb(II)has been studied both by maize stem and rice husk powder. The equilibrium concentration of Pb(II) has been attained in 60 minutes and showed the best fit in the first-order reaction and Langmuir adsorption model. SEM images before adsorption and after adsorption confirmed the insertion of Pb(II) ions onto the surface of biosorbents. © 2021, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma.
