Effect of activation factors on adsorption of cationic dye, methylene blue, by activated bentonite
The aim of this investigation was to study the relationship between activation factors and adsorption of cationic dye, methylene blue MB, by activated bentonite. The adsorption index was investigated as a function of acid type, time and temperature. A commercial bentonite was selected as a starting material and the effect of heat treatment on MB adsorption were determined in a batch setup. Thou...
متن کاملAdsorption Removal of Humic Acid from Water Using a Modified Algerian Bentonite
In this study, the main objective is the preparation and the characterization of a modified Algerian bentonite based adsorbent by intercalation with hexadecyltrimethylammonium bromide (HDTMA). Natural and modified bentonites were characterized using thermogravimetric analysis (TGA), X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The X-ray results indicate that the geometry of the int...
متن کاملAdsorption of Anionic Dyes on Poly(N-vinylpyrrolidone) Modified Bentonite
A composite based on poly(N-vinylpyrrolidone) (PVP) and sodium bentonite was prepared by a simple method. Structural characterizations of the bentonite and the composite were performed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The TGA analysis showed a low loading of the polymer in the bentonite. XRD analysis confirmed a mod...
متن کاملThermal and chemical modification of bentonite for adsorption of an anionic dye
Raw bentonite (RB), a known low-cost versatile clay was used as an adsorbent. RB was treated thermally and chemically to increase its adsorption capacity. For thermal treatment (TTB), the bentonite was heated at 400 °C for 60 min, and for the chemical modification, its surface was treated by cetyltrimethylammonium bromide (CTAB) to prepare organo-modified bentonite (CTAB-B). The removal of Cong...
متن کاملOptimization of Acid Blue 113 Adsorption from Aqueous Solutions by Natural Bentonite Using Response Surface Model: Isotherm and Kinetic Study
Background & objectives: Dyes are one of the main environmental pollutants of textile industrial wastewater which are toxic, carcinogenic, mutagenic, and non-biodegradable. Therefore, in this study, Response Surface Methodology (RSM) was used to investigate the operational parameters and determine the optimum conditions for the removal of acid blue 113 in the presence of bentonite. Methods: The...
