“…The adsorption is an excellent alternative selection especially using inexpensive and high adsorption capacity adsorbent without requiring any additional pre-treatment step before application. Adsorption is superior to other wastewater treatment techniques in terms of its initial cost, flexibility and simplicity of design, ease of operation and insensitivity to toxic pollutants [10][11][12][13][14][15].…”

This article presents two aspects environnementals: valorization of oil shale ash (OSA) of oil industry on the one hand, and on the other hand to study the effectiveness of cation adsorption of dye such as the Methylene blue (BM) on material (OSA).In this context, we carried out a parametric study of adsorption, in particular, the time of contact, the pH, the amount of the adsorbent, the temperature and the stirring velocity. A study of the kinetics of adsorption was carried out by two models: pseudo-first order and pseudo-second order, and a modeling by the isotherms of adsorption while basing itself on the models of Langmuir and Frendlich. The maximum capacity of adsorption of BM on OSA is of 2,464 mg/g, for a concentration of BM of 5 mg/L, an amount of adsorbent of 2 g/L. Material OSA was characterized by several methods such as diffraction of x-ray (DRX), electronic scan microscopy (MEB), electronic microscopy in transmission (MET), x-ray fluorescence (FX), and the infra-red Spectroscopy with transforms of Fourier (FTIR). In addition, the economic aspect of the use of OSA makes important the re-use of these materials considering their capacity to regenerate itself.

“…Therefore, dyes wastewater was usually treated by physical and/or chemical methods, such as coagulation and flocculation [5], membrane separation [6], activated carbon adsorption [7], electrochemical removal [8], and photochemical degradation [9]. However, for the developing counties, these methods are still too expensive to be used widely.…”

“…However, it is carcinogenic. The common Rhodamine B removal processes include: physical-chemical, chemical, and biological methods, such as coagulant sedimentation (Sadri Moghaddam, Alavi Moghaddam, & Arami, 2010), membrane separation (Sachdeva & Kumar, 2009), adsorption(D. Karadag, Turan, Akgul, Tok, & Faki, 2007), chemical oxidation (El-Desoky, Ghoneim, El-Sheikh, & Zidan, 2010), ion exchange method (Labanda, Sabaté, & Llorens, 2009), and aerobe and anaerobe degradation methods (Li, Zhang, Lin, Han, & Lei, 2010). Among these, the adsorption method is regarded to be an effective method for the removal of dyes from water (Chatterjee, Lee, Lee, & Woo, 2009).…”

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.
