摘　　要：以羊栖菜生物炭为原料,采用CO2物理活化法制备中孔活性炭。应用响应曲面中心组合法设计实验,考察了活化温度、活化时间及CO2流量对制备的活性炭吸附亚甲基蓝的影响及其交互作用,并采用N2吸附脱附对所制备的活性炭进行表征。结果表明,当活化温度为900℃,活化时间为30 min,CO2流量为1.8 L/min时,制备的活性炭的比表面积为1 329 m2/g,其对亚甲基蓝的吸附值高达235 mg/g,总孔体积为1.176 9 m L/g,中孔率为65%。Mesoporous activated carbon has been prepared with Sargassum fusiforme biochar as raw materials by CO2 physical activation.The experiments have been designed by response surface central composite method and the in-fluences of activated temperature,activated time,CO2 flow rate on the adsorption of the prepared activated carbon for methylene blue(MB)and its interaction investigated.The prepared activated carbon is to be characterized by nitrogen adsorption-desorption method.The results show that when activated temperature is 900℃,activated time 30 min,and CO2 flow rate 1.8 L/min,the BET specific surface area of the prepared activated carbon,adsorption value for me-thylene blue,total pore volume,and mesopore rate are 1 329 m2/g,235 mg/g,1.176 9 mL/g,and 65%,respectively.
