Kinetic and Isothermal Studies on the Adsorptive Removal of Direct Yellow 12 Dye from Wastewater Using Propionic Acid Treated Bagasse

Abstract

The industries, such as plastics, paper, dyestuffs, and textile use dyes for their products by consuming substantial volumes of water. Subsequently, they cause a considerable amount of colored wastewater. Therefore, wastewater from industries must be treated before being discharged into the environment. The modern consideration has been focused on the direction of numerous natural solid constituents that are proficient in eradicating contaminants from water at low cost. Such adsorbent which can be used for dye removal from the wastewater is sugarcane bagasse. Our findings revealed that the sugarcane bagasse acts as an efficient adsorbent. It was very efficient to adsorb the direct yellow 12. Dyes removal ability of adsorbent at diverse flow degree, initial dye concentration, contact time, particle size and pH were studied, and superior results were found.
