“…Similar trends were shown by Ma et al (2014) and Xiao et al (2012). But an ascendant trend and smooth trend were obtained by Tongpoothorn et al (2011) andWang et al (2009), respectively. With the increase in variables, the reactions become more intensive, which contribute to the development of internal microporous cavities, resulting in increasing surface area.…”

Sugar beet pulp is an abundant, renewable and low-cost precursor for production of activated carbon. In the present study, sugar beet pulp based activated carbon was prepared by using phosphoric acid as activating agent for adsorption of methylene blue. The conditions of preparation process had a significant influence on the adsorption of methylene blue, and the optimal preparation conditions were obtained as follows: liquid-to-solid ratio of 5, temperature of 450°C and phosphoric acid concentration of 3 mol/L. The properties of sugar beet pulp based activated carbon were characterized by nitrogen adsorption isotherm. The adsorption increases as the increase of contact time, adsorption temperature and pH, and initial concentration of methylene blue. Batch kinetic studies showed that an equilibrium time of 100 min was needed for the adsorption, and the adsorbance of methylene blue is 244.76 mg/g at equilibration. Kinetic models, Weber's pore diffusion model and Boyd's equation were applied to the experimental data to study the mechanism of adsorption and the controlled step. The results showed that the adsorption kinetics followed the pseudosecond-order type kinetic model, intraparticle diffusion was not the rate-limiting mechanism and adsorption process was controlled by film diffusion.

“…The activation process can be divided by two types; physical activation and chemical activation. However, chemical activation is widely applied because of its lower activation temperature and higher product yield compared with physical activation [2]. With many earlier studies, the activated carbons from agricultural wastes were always studied on its characteristic and adsorption efficiency.…”

“…Consequently, they are determined to be the precursors used for the production of activated carbon that commonly used as adsorbents. Activated carbons have exceptional adsorption properties because of their high surface area, large adsorption capacity and fast adsorption kinetics [2]. From previous studies, many agricultural wastes such as Jatropha curcas fruit shell [2], coconut shell [3], corn cob [4] Latiflorus [5], mangosteen shell [6], oil plam shell [7] and jackfruit shell [8] have been studied for preparation of activated carbon because of their proper properties.…”

Abstract-Rice from Thailand is the top ranking of the world. The by-product of rice manufacturing is rice husk, which its usefulness is not fully attempt. The aims of research are to make value-added activated carbons of rice husk and to study the optimum conditions for gasoline adsorption using these activated carbons as adsorbents. All samples were analyzed for gasoline adsorption by gas chromatograph-mass spectrometry (GC-MS). The activated carbon of rice husk, which activated by H 3 PO 4 at temperature of 450 °C, has the highest adsorption capacity. According to gasoline adsorption study, the optimum conditions were 0.1 g of activated carbon, 70 °C of adsorption temperature and 30 minutes of adsorption time. Physical characterization of the activated carbon obtained was performed by scanning electron microscopy (SEM). The results present that the activated carbon of rice husk possesses a high apparent surface area (S BET = 336.35 m 2 /g). They thus encourage the use of activated carbon of rice husk as an adsorbent for the qualitative analysis of gasoline in order to apply for gasoline sampling in arson case and to reduce the analysis cost from commercial adsorbent.

“…Activated carbon [5][6] is the commonly used adsorbent for removal of dyes and phenolic compounds. Activated carbons are the amorphous form of carbon characterized by high surface areas, micropore volumes, large adsorption capacities, fast adsorption kinetics and relative ease of regeneration [7] It has wide applications like removal of organic, inorganic pollutants from drinking water and as catalyst support. Adsorption capacity of activated carbon mainly depends on its porosity and surface area.…”
