Magnetic field assisted adsorption of methyl blue onto organo-bentonite
Source abstract
Abstract
Abstract The influence of adsorbent dosage, initial dye concentration, pH value, intensity of magnetic field and exposure types of the magnetic field on the adsorption of methyl blue were examined. The optimum condition was pH 7.0–8.0, magnetic exposure at the bottom due to the action of Lorentz force at an adsorbent dosage of 1.0 g/L and initial MB concentration 100 mg/L. The adsorption data were fitted by Freundlich model. The magnetic field improved the adsorption coefficient (Kads.) of the Freundlich model by 49%. The pseudo-second order rate constant (k2) of the adsorption kinetics was increased by 143%. The application of magnetic field enhanced the adsorption ability and obviously affected the adsorption behavior of the organo-bentonite.
