Abstract: Adsorption of pollutants on chemically modified agro-waste materials is a suitable alternative of costly methodologies of wastewater treatment. In this work, the dried leaves of Bassia longifolia had been used for removing methylene blue (M.B) dye from textile effluent after chemically modifying them with tartaric acid. All the operational parameters of adsorption were optimised and employed for isothermal modelling of equilibrium data for determining the mechanism of dye removal from water. Correlation coefficient values of Langmuir and Freundlich isothermal linear relationships indicated that both chemisorption and physiosorption are involved in removing this cationic dye from water. Maximum adsorption capacity of tartaric acid modified Bassia longifolia leaves is 30.74 mg/g of the adsorbent. Spontaneity of this process is clear from negative values of ΔG° and separation factor values, which are less than unity. These results suggested that tartaric acid modified Bassia longifolia leaves can be employed for wastewater treatment efficiently in an economical and benign way.
