Abstract

The environment is severely harmed by wastewater released from the textile industry. Few of the contaminants detected in these waters, including surfactants and dyes, have proved to be recalcitrant to standard physico-chemical processes, and non-biodegradable. Current techniques of remediation stell unsuccessful, and their toxicity in treated samples may result in significant health problems. This study focuses on the preparation of modified bentonite-based composites (P1 and P2) for the removal of methylene blue (MB) dye. The influence of several variables, including pH and dye solution concentration was investigated. The equilibrium period for adsorption of (MB) on P2 is 180 minutes. The kinetic studies of (MB) adhere to the pseudo-second-order model, while the Freundlich model describes the adsorption isotherm. The adsorption capacity of (MB) onto P2 is 192.30 mg.g-1. Temperature positively influences the adsorption of (MB) by P2. The enthalpy values reveal the physisorption of this process.
