Successful utilization of rice husk, which accounts for approximately 20% of weight of rice grain, carries strong implications in reducing agricultural waste and devising cost-effective materials for environmental applications. This review focuses on summarizing approaches to produce activated carbon, an important adsorbent material used in wastewater treatment, from rice husk material. Activated carbon from rice husk has been synthesized by methods such as chemical, physical and physicochemical. Which, physicochemical methods were mainly used with activators such as KOH, NaOH, ZnCl2, HCl, and K2CO3. The structural properties of the materials were analyzed using physical analytical methods. The shape of rice husks activated carbon was the same a honeycomb network, which was typical for the activated carbon. Surface functional groups and crystal structure characteristics were also noted with characteristic functional groups and crystal structures with large specific surface areas. The adsorption capacity of the material has also been specifically reported. Treatment efficiency reached 70% of pollutants such as dyes, heavy metals, phenols and other organic compounds. The kinetic and isothermal models were showing good agreement with the Langmuir, Freundlich and PSO. [ABSTRACT FROM AUTHOR] |
