Sequestering of Fe and Pb ions from Wastewater by Canarium schweinfurthii after carbonization and chemical treatment: Isothermal and Kinetic Modeling

摘要

In this paper agricultural waste; Canarium schweinfurthii was explored forthe sequestering of Fe and Pb ions from wastewater solution after carbonization and chemicaltreatment 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 pseudofirstorder as sum of absolute error (EABS) between Qe and Qc greater than that of pseudosecond 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 thesuitability of the adsorbent for sequestering of Fe and Pb ions from industrial wastewater.
