Preparation of Bamboo-Based Activated Carbon

Abstract

Experiment study on activated carbon preparation from bamboo with chemical activation and by K ₂ CO ₃ as activating agent was carried out in this paper. The effects of activation temperature, impregnation ratio and activation time on specific surface area, volume resistivity and ash content were systematically investigated. Specific surface area was estimated by BET surface area analysis. SEM analysis was used to study the structural changes among different activated carbons. XRD analysis was applied to investigate the structural parameters of the activated carbon generated from different temperatures. Optimum working condition was as follows: activation temperature of 900°C, activation time of 2 h, and impregnation ratio of 1 and the experiment results showed that specific surface area, volume resistivity, and ash content of activated carbon could reach 1264 m ² .g ^-1 , 1569 ¿¿.m and 7.14% under optimum condition, respectively.
