“…Best fit was observed by pseudo-second order kinetics model for the adsorption of perillaldehyde on these five resins. Similar phenomena have been observed in the adsorption of phenol, phenolics and rosmarinic acid on polymeric adsorbents (Zeng et al, 2009;Lin et al, 2012). According to the pseudo-second order rate constant, k 2 , the adsorption rate of the five reins is ordered as follows: HPD-100 > LS-305A > DM-21 = LS-305 > XAD-16.…”

Abstract:Magnetic composites have a wide range of potential technological applications; however the evaluation of this material for extraction of phenolic compounds has not been sufficiently studied. Due to its high toxicity and solubility the removal of phenolic compounds from the aquatic environments has critical importance. In this work polymeric composites were prepared by anchoring Ni and Co particles on sulfonatedpoly(styrene-co-divinylbenzene) PS-DVB. The PS-DVB beads were synthesized by suspension polymerization and reacted with acetyl sulfate, aiming to obtain sulfonated copolymers. All materials were capable of removing phenol from aqueous solutions. The phenol adsorption kinetics was influenced by the polymer porosity and swelling capacity in water. The composite derivative of the more porous copolymer impregnated with nickel (C1SNi) was the most efficient in phenol removal, with the sorption equilibrium being established more rapidly than for the other composites. The pseudo second-order model was more adequate to describe the phenol adsorption process for the composite C1SNi. The Langmuir model describes successfully the phenol removal by this composite.

“…Ingestion of phenols through water in concentration from 10 to 240 mg L -1 for a long time causes mouth irritation, diarrhea, and excretion of dark urine and vision problems (Hegazy et al 2013;Asma and Zainal 2009). The WHO (2008) recommended threshold limit of phenol in potable water as 0.001 mg L -1 (Zeng et al 2009), while US Environmental Protection Agency (EPA) recommended the permissible limit of phenols in the wastewater\1 mg L -1 (Eahart et al 1977). Phenols can be removed from the aqueous solution through oxidation, precipitation, ion exchange, biodegradation, ultrasonic degradation, solvent extraction, ozonization and decomposition by fenton reagent (Aksu and Yener 2001;Rengaraj et al 2002).…”

Artificial Neural Network model and isotherm study were done to predict the removal efficiency of phenol. An inexpensive adsorbent was developed from orange peel ash (OPA) for effective uptake of phenol from aqueous solution. The influence of different experimental parameters (initial concentration, pH, adsorbents dose, contact time, stirring rate and temperature) on phenol uptake efficiency was evaluated. Phenol was adsorbed by the OPA up to maximum of 97.34 %. Adsorption of phenol on OPA correlated well with the Langmuir isotherm model, implying monolayer coverage of phenol onto the surface of the adsorbent. The maximum adsorption capacity was found to be 3.55 mg g -1 at 303 K. Pseudo-second-order kinetic model provided a better correlation for the experimental data. Moreover, the activation energy of the adsorption process (E a ) was found to be -18.001 kJ mol -1 indicating physorption nature of phenol onto OPA. A negative enthalpy (DH°) value indicated that the adsorption process was exothermic. Again multi-layer Neural Network model was in very good agreement with the experimental results.
