This paper investigates the application of Activated Carbon derived from Waste Tea Bags (AC-WTB) in the removal of As(III) and Pb(II) ions from aqueous solutions.
Batch experiments were conducted to determine the effect of varying adsorption parameters on the removal of aqueous As(III) and Pb(II) ions; the data collected were compared to known adsorption isotherms.
The adsorption of As(III) ions was found to be maximum (80%62.33) at pH 5 and that of Pb(II) ions was found to be optimum (58%61.89). The adsorption capacity, Qo, (mg g-1) of As(III) is higher than that of Pb(II) ions and were found to be 7.348 and 3.791 respectively. The affinity of the two metals for the adsorbent surface in terms of b is higher for As(III). The Freundlich level of conformity for As(III) is to a high extent compared to the Langmuir adsorption isotherms as indicated by higher correlation coefficients values of 0.9917. Original value of paper: A cheap and readily available adsorbent is proposed for tackling harmful metals in aqueous solutions, thus meaning a reduction in the potential of water borne diseases.
