“…The adsorption capacity of any adsorbent and adsorption mechanism can be predicted from equilibrium adsorption isotherms [28]. Langmuir, Freundlich and Dubinin-Radushkevich (D-R) adsorption isotherms are used to understand the adsorption of SO dye onto MDMLG.…”

“…There are various methods to remove dyes from sewage, such as adsorption, biodegradation, coagulation, filtration and reverse osmosis (Han et al 2010;Yu et al 2010). Surface adsorption is considered to be an efficient process among color removal methods due to its low cost, ease of operation and high efficiency (Alpat et al 2008;Gök et al 2010).…”

We have used nanoscale zero-valent iron particles to remove Acid Green 25 (AG-25) dye from aqueous solution and have studied the effects of important variables, such as dye concentration, catalyst amount, pH and time, on the dye removal process, optimized by the Taguchi approach. Sixteen experiments were required to study the effect of all four parameters on removal of the dye. Each experiment was repeated three times to calculate the signal/ noise (S/N) ratio. Based on the S/N ratio, optimum values of 4, 0.6 g, 120 s, 20 mg L -1 were obtained for pH, catalyst amount, time and dye concentration, respectively. At the optimized condition, the removal percentages of AG-25 dye was found to be 96.82%.

“…Mostly, after the surface properties of bentonite are changed by using modifiers, such as 1,6-diamino hexane, cetyltrimethylammonium bromide, some acids, and iron organo-inorgano pillars, bentonite is used as an adsorbent. In literature, there are many studies on the textile dyes obtained from aqueous solutions by adsorption onto modified bentonite [24][25][26][27]. However, there is a couple of study in this subject that uses natural bentonite, which is Na + -bentonite [28][29][30].…”

A B S T R A C TThe adsorption of Basic Yellow 28 (BY28) onto bentonite in a batch system was carried out at temperatures of 20 and 40˚C. The initial dye concentrations were in the range of 100 and 300 mg/L based on the total organic carbon (TOC) content of the dye solution. The effects of contact time, initial pH, and initial dye concentration on BY28 adsorption by the bentonite have been studied. BY28 removal was observed to increase until equilibrium, with increasing contact time and initial dye concentration, and the adsorption capacity of bentonite was seen to increase with increasing pH from 3 to 8. Adsorption efficiencies up to about 98.1% were obtained based on the TOC at various adsorption conditions. The adsorption process was determined to follow the pseudo-second-order adsorption kinetics. Kinetic parameters, rate constants, equilibrium adsorption capacities, and correlation coefficients of the adsorption kinetic models were calculated and discussed. The experimental isotherm data were analyzed using the Langmuir and Freundlich equations. The Langmuir isotherm represents that the adsorption of BY28 is indicating a very good mathematical fit compared with the Freundlich equation. The maximum monolayer adsorption capacity (q max ) of the Ca-bentonite was determined as 94.3396 mg/g for 20˚C and 99.0295 mg/g for 40˚C.
