On The Characterization, Use and Wastewater Detoxification Potential of Pyrolyzed Moringaoleifera Pods and Shells PART B: Sorption Isotherm, Kinetic, and Thermodynamic study
Journal Title: Chemical Methodologies - Year 2018, Vol 2, Issue 0
Abstract
In this study, previously estimated tannery effluent with high pollutant (Cr) load of 987 mg/L was detoxified using pyrolysed Moringaoleifera Pods(PMOP)and Shells (PMOS).A performance assessment of the gained and characterized adsorbents was based on equilibrium, rate and thermodynamic studies.An investigation was carried out on equilibrium studies using isotherm models (Langmuir, Freundlich, Dubinin-Radushkevich and Temkin isotherm models).The maximum adsorption capacity of PMOS is 277.3 mg/g. Sorption rate is best explained using the Pseudo-second order kinetic model with diffusion through the liquid film surrounding the solid sorbent. Comparison of performance with commercially available activated carbon shows no statistical significance at p< 0.05.
