外文摘要：Converting waste fiber to high value-added carbonaceous materials has been considered as an effective and affordable route in response to the increasing volume of waste fiber in recent year. In this study, we are the first to prepare activated carbon powder derived from cashmere guard hair as a renewable waste protein fiber, using a chemical activation method at different impregnation ratios of K2CO3/cashmere guard hair char and activation temperatures ranging from 400celcius to 600celcius. Characterization of the activated carbon powder was carried out by morphology study, specific surface area study, and adsorption study. Results have shown that the increase of the impregnation ratio and the activation temperature created more microporous structure in the activated carbon powder, and then increased the specific surface area of the activated carbon powder as well as the amount of methylene blue adsorbed. However, the carbon yield increases with the increase in the impregnation ratio of K2CO3/cashmere guard hair char and decreases with the increase in the activation temperature. The activated carbon powder, activated by the condition of 1:2 K2CO3/cashmere guard hair char impregnation ratio and 600celcius activation temperature, has a specific surface area of 764.86 m(2)g(-1)and a carbon yield of 14.07 wt%. Compared to the activated carbon powder derived from fine merino wool fibers, the activated carbon powder derived from cashmere guard hair has higher carbon yield, surface area, and total pore volume, showing a superior adsorption performance.
