The sorption behavior of dye remazol yellow using surfactant modified zeolitic rock and a carbonaceous material obtained by pyrolysis of sewage sludge and treated with HCl (1.0%) solution was determined. The kinetic and sorption isotherms experimental results were best adjusted to the pseudosecond order model and to the Langmuir-Freundlich isotherm model which indicate that the sorption process is chemisorption on heterogeneous materials. Remazol yellow could be removed from the saturated modified zeolitic material by different processes, unfortunately, the surfactant was removed together with the dye, the best results were found using Fenton's reagent. Thermal treatment was the best method found to remove the dye from the carbonaceous material.

“…This modification using a surface active agent is a key technology for the application of raw zeolites in wastewater treatment (Leyva-Ramos et al, 2008;Zeng, Woo, Lee, & Park, 2010). Currently, many research studies have investigated these modified zeolite's adsorption performances with many dyes, such as reactive black 5, reactive red 239, reactive yellow 176, acid orange 8, and acid orange II (Ayşegul, Ozgur, Abdullah Zahid, & Mustafa, 2008;Benkli, Can, Turan, & Çelik, 2005;Jin, Jiang, Shan, Pei, & Chen, 2008;Dogan Karadag, 2007;Torres-Pérez, Solache-Ríos, & Olguín, 2007). However, few studies have been conducted regarding the removal of Rhodamine B in water using zeolites which have been modified by a surface active agent (Hayakawa, Dobashi, Miyamoto, & Satake, 1997;Hayakawa et al, 2000).…”

In this study, modified zeolites were prepared through the modification of raw zeolites, using hydrochloric acid (HCl) and cetyl trimethyl ammonium bromide (CTAB), whose properties were then characterized by a Zeta Potential Meter and an X-ray diffractometer. Also, the adsorption mechanisms were investigated in depth. The experimental results indicated that, in terms of the adsorption capacity of Rhodamine B in water, the modified zeolites were more favorable than the raw zeolites. As the dosage of adsorbent increased, the removal percentage of Rhodamine B in the water increased, while the unit adsorption capacity decreased. The pH value of the solution, and reaction temperature imposed little effects on the adsorption of the Rhodamine B. In accordance with the adsorption thermodynamic results, Langmuir and Freundlich isothermal adsorption models were able to accurately describe the adsorption of Rhodamine B in water by the modified zeolites. The fitting results had a higher correlation when using a Freundlich isothermal model. At 303 K, the static saturated adsorption capacity was 4.41 mg/g. The kinetic results demonstrated that the adsorption of Rhodamine B in water using modified zeolites fit well with the pseudo-second-order kinetic model.

The surface of barley straw, an agricultural waste, was modified chemically using a cationic surfactant hexadecylpyridinium chloride monohydrate (CPC) and used as an adsorbent for removal of Reactive Blue 4 (RB4) from aqueous solution. The raw and surfactant-modified barley straws (SMBS) were characterized by Fourier transform infrared and elemental analysis. The stability of CPC adsorbed on straw surface was evaluated by exposing to water and organic solvents. The adsorption was performed on removing RB4 from wastewater in a batch adsorption system. The effects of contact time, initial concentration of dye and pH of solution on RB4 uptake were investigated and discussed. It was found that the removal percentage of RB4 increased with the increase in contact time. Adsorption was favorable at acidic condition and the maximum removal of 100% was obtained at pH 3. Dye-loaded SMBS was stable and percentage of desorption was less than 7% in water. The kinetic studies revealed that the kinetic data fitted well to the pseudo-second-order model. The isotherm study also indicated that RB4 adsorption on SMBS matched well with the Langmuir model other than the Freundlich model. The maximum adsorption capacity determined from the Langmuir isotherm was 29.2 mg g −1 at 25
