Characterization and application of activated carbon produced by H3PO4 and water vapor activation

Removal of lead from water using biochars prepared from hydrothermal liquefaction of biomass

“…This problem could be simply avoided by carbonization of the raw materials. Recently birch wood was successfully converted to carbonaceous material and the product showed high mercury removal efficiency from aqueous solution [8]. Activated carbons, prepared from rice husk and sugarcane bagasse, had good adsorption capacities with respect to arsenic, humic acid and phenol [9].…”

Characterization of Pyrolysis Products Obtained During the Preparation of Bio-Oil and Activated Carbon

“…The large surface area results in a high capacity for adsorbing chemicals from gases or liquids. Activated carbons are versatile adsorbents with a wide range of applications such as adsorbents for treatment and purification of water, air as well as various chemical and natural products (Abdel-Nasser & El-Hendawy, 2005; Budinova et al, 2006). The increasing use of activated carbon is due to the necessity of environmentally friendly processes and also for material recovery purposes.…”

Adsorption for Dyes on Activation Carbons from Japanese Cedar Wood Prepared by Precarbonization and Two-stage Composite Activations with Wood Ash and Steam

“…The 0.00-850 had the minimum adsorbance, which was 222.2 mg/g and 312.5 mg/g, respectively. According to the results, the BY2 and BG4 dyes adsorption quantity increased with the S BET and S ex of ACss other than K 2 CO 3 -1.00-800 (Table II), because the developed mesopores' structure is connected to the micropore channel, which is favorable for the adsorption result of ACs [70]. However, the K 2 CO 3 -1.00-800 had high S BET 1537 m 2 /g and S ex 1162 m 2 /g, but less micropores (V mi 0.16 cm 3 /g, V mi /V tot 18.6%, Table II), meaning it is disadvantage to adsorbing micro-molecular adsorbate [21], [23], [37], [49], [71]- [75].…”
