“…Although the thermodynamic and kinetics of organic compounds adsorption from gas phase by zeolites have been investigated, Radeke et al [24] have shown that straightforward extrapolation is not possible from the gas-phase adsorption of organics in the presence of water vapor to the separation of organics from liquid water using dealuminated Y zeolites as adsorbents.…”

“…Literature contains number of methods such as oxidation with ozone/hydrogen peroxide [5], ion exchange [6], electrochemical oxidation [7], reverse osmosis [8], photo-catalytic degradation [9], and adsorption [10] which have been used for the removal of phenols. The treatment of with active carbon, silicates and polymer resins are considered to be an effective method for the removal of phenol from wastewater because of its large surface area, micro-porous nature, high adsorption capacity, high purity and easy availability [11]. Phenol removal by adsorption process remains the best treatment of choice as it can generally remove all types of phenols in a simple and easy operation.…”

Abstract. The potential of tendu (Diospyros melanoxylon) leaf refuse from bidi industry waste to remove phenol from aqueous solution was studied. For this purpose, the tendu leaf refuse was carbonized by subjecting it to chemical treatments with sulfuric acid. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, phenol concentration, adsorbent dose and pH. Adsorption equilibrium of tendu leaf refuse and chemically carbonized tendu leaf refuse was reached within 2 hr for phenol concentration 10-25 mg/l and 1 hr for phenol concentration 20-200 mg/l, respectively. The adsorption of phenol decreases by the increase of the pH value of the solution. The kinetic data followed more closely the pseudo-second-order chemisorption model. The adsorption data were modelled by using both Langmuir and Freundlich classical adsorption isotherms. The maximum adsorption capacity of chemically carbonized tendu leaf refuse as per Langmuir model was 4 times higher than that of raw tendu leaf refuse. The results illustrate how tendu leaf refuse, a solid waste disposal menace from bidi industry, can be used as an effective biosorbent for phenol in aqueous solution.

“…Sorption is superior in simplicity of design, initial cost, ease of operation and insensitivity to toxic substances in comparation with other physicochemical and biological techniques, such as the membrane filtrations coagulation/flocculation, ion exchange, advanced oxidation (chlorination, ozonation), flotation, chemical reduction and biological treatment (bacterial and fungal biosorption, biodegradation in aerobic or anaerobic conditions) 2 . Several investigations have studied the sorption of phenol on active carbon because of its large surface area, micro-porous nature, high adsorption capacity, high purity and easy availability [3][4][5][6][7] . Natural materials that are available in large quantities or certain waste form agricultural operations may has potential to be used as low cost adsorbents, as they represent unused resources, widely available and are environmentally friendly.…”

In order to provide physical support for chitosan and increase the accessibility of the binding sites for sorption process applications, chitosan was coated on the surface of montmorillonite. For the optimization of the sorption of phenol on chitosan coated montmorillonite (CCM), effects of pH, initial concentration and temperature on the sorption of phenol by CCM were investigated. In order to find the sorption characteristics, the isothermal data were applied to Langmuir and Freundlich linear isotherm equation, and the thermodynamic parameters (ΔH, ΔG and ΔS) were also calculated according to the values of binding Langmuir constant K L . The L type sorption isotherm between phenol and CCM suggests a relatively high affinity between the adsorbate and adsorbent, and the mechanism involved in the association of phenol with CCM were proton transfer, hydrogen bonding, London-Van der Waals forces because of lots of the OH and NH 2 groups in the chitosan chain. The negative ΔH constant confirmed that the more phenol was adsorbed by CCM at lower temperature and the driving force for sorption process is an enthalpy effect. The kinetics of the sorption process of phenol on CCM were also investigated using the pseudo-first order and pseudo-second order kinetics, results showed that the second order equation model provided the best correlation with the experimental results. It was reached that modification of chitosan with montmorillonite increased the possibility of utilization of chitosan for phenol remove from aqueous solution.
