“…Several adsorption isotherms have been studied such as Langmuir and the Freundlich Isotherms which used to determine the adsorbates layer formation on the surface of adsorbent [17]. The analysis of the equilibrium data by fitting them into different isotherms models is a very important step to find a suitable model that can be used for design purposes [15].…”

“…Adsorption isotherm is useful to describe how solutes interact with adsorbents and very important to evaluate feasibility of the adsorbent-adsorbate system. The adsorption isotherm indicates how the adsorption molecules distribute between the liquid phase and the solid phase when the adsorption process reaches an equilibrium state [15]. The adsorption equilibrium data obtained for the untreated and treated activated carbon were fitted into two different isotherms models to determine the most suitable model to represent the adsorption process.…”

Phenolic compound can be an inhibitor during acid pre-treatment process in the conversion of biomass into bioenergy and consequently reduces the production yield. Thus, this study aimed to investigate the potential use of activated carbon from coconut shell for phenolic compound removal and gallic acid was used as model phenolic. Granular activated carbon was treated by using 20% concentration of phosphoric acid to its properties and function. Acid treated and untreated activated carbon were characterized in term of morphology, surface functionalities and material phase by means of SEM, FT-IR and XRD. Few parameters that influenced the removal of gallic acid were studied which included the effect of adsorbent dosage, initial concentration, contact time, and pH. It is observed that the acid treated activated carbon was successfully remove the gallic acid for about 97% using of 0.5g/L adsorbent dosage, with initial concentration of 100 mg/L, at pH value of 4 and 150 minutes contact time. The adsorption behavior was fixed with Langmuir isotherm fixed the experiment data which indicates homogenous adsorption. These experimental results also revealed that coconut shell based activated carbon is viable cheaper adsorbent for phenolic compound removal.

“…Nevertheless, at low contaminant concentration and large wastewater volume, the adsorption technique is one of the most effective methods [6]. Various adsorbents have been investigated for the removal of phenol from water, namely PANI [7], bentonite [8], zeolite [9,10], carbon xerogels [11], gel [12], scoria stone [13], crab shell chitosan [14], and coal [15].…”

Activated carbons (ACs) obtained from coffee husk by KOH activation at 650 (ACK-650) and 750 o C (ACK-750), were used as an adsorbent for the adsorption of phenol from aqueous solution. The ACs was characterized by SEM, EDX, BET, and Boehm titration techniques. The experimental equilibrium data of phenol adsorption was analyzed by eight isotherm models, which are four two-parameter equations (Langmuir, Freundlich, Elovich, and Temkin) and four three-parameter equations (Redlich-Peterson, Sips, Radke-Prausnitz, and Tóth). The results reveal that in general, three-parameter isotherms can provide better prediction than two-parameter isotherms. The best fit for ACK-650 sample is Sips isotherm, while for ACK-750 sample is Redlich-Peterson isotherm. Isosteric heat and thermodynamic parameters ΔG o , ΔH o , and ΔS o of the adsorption were determined, and the results showed that the adsorption of phenol was exothermic and physical in nature. A scale-up of a batch system is designed for 2 to 10 L phenol with an initial concentration of 100 mg L -1 .

The complete oxidation of isopropanol in its liquid phase at a low temperature was studied in the presence of zinc oxide (ZnO). This solid was prepared with the precipitation method. Structural analysis (infrared in Fourier transform and diffraction of X-rays) and textured (adsorption/desorption of N2) were conducted for the wurtzite structure results, an IV type isotherm with a type H3 hysteresis. This solid presents a good catalytic activity against the complete oxidation of isopropanol, a constant of selectivity equal to 1; however, the studied temperatures were 40, 60, and 80°C. In addition, a kinetic study of the oxidation was performed and showed that the reaction follows a successive mechanism isopropanol-acetone-carbon dioxide. The low value of the apparent energy of the activation of this solid confirms the high value of the initial rate of the catalytic oxidation reaction of isopropanol in the temperature range studied.
