Abstract
In this paper agricultural waste; Canarium schweinfurthii was explored for the sequestering of Fe and Pb ions from wastewater solution after carbonization and chemical treatment at 400oC. Optimum time of 30 and 150 min with percentage removal of 95 and 98% at optimum pH of 2 and 6 was obtained for Fe and Pb ions. Kinetics model followed pseudofirst order as sum of absolute error (EABS) between Qe and Qc greater than that of pseudo second order. Parameters evaluated from isothermal equation (Freundlich and Langmuir) showed that KL and QO for Fe > Pb and R2 for Langmuir> Freundlich. The study reveals the suitability of the adsorbent for sequestering of Fe and Pb ions from industrial wastewater. ©JASEMKeywords: Adsorbent; Pb; Fe; Kinetics and Isotherm
Highlights
Man’s activities in the environment have greatly led to an increase in concentration levels of heavy metals
Heavy toxic metals entered into the environment through wastewater from metal plating industries and industries of lead, cadmium and nickel batteries, phosphate fertilizer, mining, pigments electroplating, Corrosion, and other industrial waste (Ahalya et al,. 2005)
Chemical activation of carbonized adsorbent : 10 g of carbonized endocarp of Canarium Schweinfurthii was transferred into a beaker containing 50 cm3 of 0.5 molar trioxonitrate (V) acid
Summary
Man’s activities in the environment have greatly led to an increase in concentration levels of heavy metals. These have generated a lot of interest in pollution studies. Carbonaceous surfaces, typically in the form of soot particles, play an important role in the chemistry of adsorption These carbons are characterized by a high degree of chemical and morphological heterogeneity that affects their function. These characteristics affect their interactions with molecular adsorbates and, the adsorption capacity (or efficiency) and catalytic activity. This work is aimed at optimizing the function and usefulness of evaluating the isothermal and kinetic model of treating Fe and Pb ions in waste water using carbonization and chemical treatement of Canarium schweinfurthii
