Abstract

Removal of methylene blue (MB) from aqueous solutions by river sand using batch and column techniques was investigated. It was observed that the maximum removal of MB was achieved at pH 4, 45 minutes contact time and 500 g/L dosage adsorbent river sand. Adsorption data were better fitted to the Langmuir isotherm. Pseudo second-order kinetics was most suitable to explain the kinetic study. The removal of methylene blue by column adsorption of river sand was ranged between 29.01% and 99.99%. It was found that the adsorption of methylene blue by river sand was more conformed to the model Thomas. In different flow rates study, flow rate of 10 mL/min in the column adsorption can better remove the methylene blue. This study shows that the river sand cannot undergo desorption.
