“…The design of adsorption system play a crucial role in order to generate high quality treated effluent. 16,17 Activated carbon has been generally utilized for this reason in view of its high adsorption capacity; however, its high cost tends to limit its use. In the past few decades, much research has been focused on the development of adsorbents from natural sources, for example, naturally occurring clays, zeolites, and other cheap and accessible solid materials to remove dyes from wastewater.…”

The main objective of this research is to study the adsorption behaviour of malachite green and methylene blue dyes onto the surfactant modified natural clays. The results of SEM, XRD, IR, and thermal analysis confirms the intercalation of organic moiety in to the clay. The adsorption results show that pseudo-first order kinetics best fitted for both the dyes adsorbed on organo-clay. The data also reveals that both dyes are in a good agreement with Langmuir isotherm in both types of modified clays. The value of separation factor, R L , from Langmuir equation and Freundlich constant, n, give an indication of favourable adsorption. The maximum adsorption capacity q m based on Langmuir model was found to be 294-303 mg/g at 25 °C, is in good agreement with the experimental values.

“…The results show that the intercalation caused an increase of inter-laminar distance that was 14.97 Å for raw clay and reach to 25.34 and 19.46 Å for HDTMA and DDMA clay, respectively. [5,7,8,[15][16][17][18][19] Thus, the intercalation of HDTMA and DDMA was only into the interlayer of smectite component, while the interlayer of illite was intact. These results are in agreement with the intercalation of other cationic surfactant as octadecyltrimethylammoniumchloride and dioctadecyldimethylammoniumchloride in Na + -montmorillonite, which gives a maximum layer expansion of about 10 Å corresponding to the presence of a parallel or lateral layer of organic molecules extended conformation.…”

Tunisian bentonites were used to prepare three modified clays: two organoclays by intercalating respectively didodecyldimethylammoniumbromide (DDMAC) and hexadecyltrimethylammoniumbromide (HDTMAC), and synthesis of NaX zeolite. The X-ray diffraction, infrared and thermogravimetric analyses enabled us to differentiate between the structures obtained. Clay materials systems were used as adsorbent for the investigation of the adsorption isotherms and saturation capacity of O-xylene, a toxic volatile organic compound, by gravimetric method at three different temperatures 20, 30, and 40°C. The absolute values of the volatile organic compound adsorbed amounts in the intercalated clays (604 mg g À1 ) were higher than for the zeolite (296 mg g À1 ). The adsorption isotherms were analysed by the Freundlich and Langmuir equations. The latter was found to describe better the equilibrium adsorption data. Mass transfer coefficient of O-xylene is evaluated using uptake curve method, and all values are in the order of 10 À2 s À1 .

“…Most of the synthetic dyes used for colourisation in different industries like textile, leather, paper, plastic and dyeing, accumulate in the environment and have highly harmful effects causes either to human beings or to aquatic life [1]. Thus, the disposal of dyes and pigments into aqueous environment is a main serious environmental problem, making discharge of highly coloured compounds from wastewater.…”

The textile effluents are toxic compounds, has a significant negative consequence on the environment, especially during its discharge in water and soil. The present work, physically activated carbon (PAC) is a low-cost effective adsorbent used to adsorb dyes from waste water because of its high adsorption abilities. The batch experiment was investigated by different variables like contact time, dye concentration, dosage of activated carbon, temperature, pH, agitation speed, activation time and desorption studies. At optimum experimental conditions, maximum removal of Brilliant Green (BG) dye has been observed to be 99%. The different adsorption isotherms were modelled to describe the equilibrium data. The adsorption data were analyzed using kinetic and diffusion models. On the basis of experimental results, the physically activated carbon showed excellent sorption properties with high dye removal capacity.
