Removal of Azo Dye (Dispersed Red 17) Using Activated Carbon and Studying the Influencing and Kinetic Factors

Abstract

One of the main environmental challenges nowadays is the removal of dyes from colored effluents, especially those from textile companies. Current techniques for color removal from wastewater are expensive and ineffective for treating a variety of such wastewater. In this work, the effective adsorbent material activated carbon produced from palm fibers is used to remove the dye. To measure the adsorption capacity, aqueous solutions with various basic Dispersed Red Dye 17 (DR17) concentrations (20-150 mg l-1, respectively) were shaken with specific amounts of adsorbents. On dye removal, the effects of adsorbent dosage, starting pH, starting dye concentration, agitation speed, and contact time have been investigated. Within 60 to 90 minutes of the start of each experiment, the majority of the dye was eliminated from the solution. As the dye removal rate reaches 82%.
