Colour Removal from Effluents Using Micromaterials

Abstract

In this study, the ability of Micromaterials to adsorb color from an aqueous solution was investigated by using flocculants and activated carbon prepared from Rice Bran, an agricultural by-product, and batch mode adsorption experiments were conducted. The influence of various factors such as initial concentration (20, 40, 60, 80 mg/L), contact time, pH (4.0-9.0), and dosage on the adsorption capacity was investigated and optimal experimental conditions were ascertained. Adsorption data were modeled using Langmuir, Freundlich, and Temkin adsorption isotherms. The results indicated that the flocculants and adsorbents could be employed as low-cost adsorbents in wastewater treatment for the removal of color.
