Valorization of natural material for the removal of an industrial pollutant

Abstract

The aim of this work is to study the possibility of adsorption of methylene blue dye by woodworking powder, The adsorption efficiency of woodworking powder increases with increasing sorbent mass and pH, and decreases with increasing initial methyl blue concentration and temperature. Kinetic experiments showed that the adsorption is fast and conforms to the pseudo-second order model, while isothermal experiments showed that the Langmuir model is the most appropriate for this adsorption, with adsorption efficiency equal to 90, 90 mg/g under optimum operating conditions.
