Abstract

Introduction: Many industrial processes use different synthetic chemical dyes for various purposes, including paper and pulp manufacturing, fabric and textile dyeing, leather treatment, printing, etc. Effluents from these industrial facilities are typically of high organic contents and color strength. (1)Aim: The main aim of this research was using tea wastes to remove METHYLENE BLUE (MB), a cationic dye with =N+(CH3)2 reactive group from aqueous solutions.Materials and methods: Tea wastes as a non-living biomass was used to remove METHYLENE BLUE (MB) as a cationic dye according to Langmuir equation that is suitable for adsorption by dead biomass. Kinetic modeling and thermodynamic equation were used to evaluate the process.Result: The maximum uptake capacity (Qmax) of METHYLENE BLUE in a batch reactor was 0.328, 0.542 and 0.659 mmol/g at 15, 25 and 40oC, respectively. The enthalpy change (∆H) and entropy change (∆S) were 11.356 kJ/mol and 20.563J/mol K respectively.Conclusion: Thermodynamic studies showed that adsorption equilibrium constant (KL) and Qmax increased by increasing temperature. The percent of MB removal with Co=0.01mM was shown about 85% at optimum conditions.
