“…This is because the terminal amino group of KH550 was protonized under acidic conditions, entering the interlayer of sericite mica by ion exchange (Lai et al, 2014). The observed d-spacings were greater than those reported in previous work under the same modification conditions or using other intercalation agents (Theng, 2012;Ding et al, 2014;Zawrah et al, 2014;Zhang et al, 2015;Siregar et al, 2018). Also, there is limited previous work on the comprehensive treatment of sericite mica combining intercalation modification and surface modification.…”

“…The specific surface area is a crucial indicator of adsorption capacity. Table-2 shows that the decrease in surface area of the modified bentonite was caused due to the binding of CTAB to the surface and relatively fine intercalated pores of bentonite, which considerably reduced the total surface area [11][12][13].…”

High concentrations of synthetic dyes observed in the effluents from industries that manufacture and process paper, leather, plastic and textiles [1]. The textile industry comprises a major proportion of industries in developing countries. The quality of produced textile is strongly affects its export. Wastewater from textile plants, which contains synthetic dyes, is discharged into rivers and natural streams; which causes several environmental problems. Acid dyes are the most problematic type of synthetic dyes owing to their intense colors, acidic nature, high solubility in water and reactive characteristics. Acid dyes impart colours to large water bodies even at low concentrations, thus reducing both the scenic value and light penetration into the water bodies needed to support photosynthesis by aquatic flora in the water body. Since, numerous dyes are toxic or carcinogenic, hence, the removal of dyes from wastewater is essential and crucial [2]. Many approaches, such as precipitation, electrodialysis, adsorption, filtration, coagulation, oxidation and membrane separation have been developed for the decolorization of water [3]. However, adsorption has been considered among the most effective techniques for the removal of dyes from water. How

Modified bentonite has been used as effective sorbent material for the removal of acidic dye (methyl orange) from aqueous solution in batch system. The natural bentonite has been modified using cationic surfactant (cetyltrimethyl ammonium bromide) in order to obtain an efficient sorbent through converting the properties of bentonite from hydrophilic to organophilic. The characteristics of the natural and modified bentonite were examined through several analyses such as Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and Surface area. The batch study was provided the maximum dye removal efficiency of 88.75 % with a sorption capacity of 555.56 mg/g at specified conditions (150 min, pH= 2, 250 rpm, and 0.5 g/100 ml). The-results-showed that with the Freundlich isotherm model the sorption data was accurately described with (R2≥0.94) in comparison with the Langmuir model under the studied conditions. The kinetic studies were revealed that the sorption follows a pseudo-second-order kinetic model which indicates chemisorption between sorbent and sorbate molecules.
