Abstract

“Waste” Jute Fiber, an agricultural “waste” by-product was converted into an effective adsorbent and the same was tested for the removal of Malathion pesticide from aqueous solution. The prepared activated Jute fiber carbon (JFC) was characterized by using Scanning Electron microscope (SEM), X-ray diffractometer (XRD), Elemental analyzer and proximate analysis methods. Adsorption equilibrium, kinetics, thermodynamics and mass transfer studies were investigated as a function of agitation time, adsorbent dose, pH and temperature. The adsorption data obtained are found to obey Langmuir isotherm model. The adsorption kinetics was analyzed by using pseudo first order, pseudo second order and Elovich models. Thermodynamic parameters of adsorption process, i.e. ?G, ?S and ?H were computed and their negative values indicate the adsorption was exothermic and spontaneous nature.
