摘要
以楠竹粉为原料,采用磷酸活化法制备楠竹活性炭,并研究其同时对水中敌草隆和3,4-二氯苯胺的吸附性能。借助傅立叶变换红外光谱、扫描电子显微镜、比表面积分析仪对样品进行形貌表征,发现其表面具有丰富的含氧官能团和发达的孔隙结构其比表面积为947.96 m^(2)/g。当楠竹活性炭添加量为4 mg时,对敌草隆和3,4-二氯苯胺的吸附量分别为70.66 mg/g和64.90 mg/g,其吸附机理类型均符合Freundlich模型与准二级动力学模型。
The preparation of activated carbon(AC) from Nanzhu was studied by chemical activation with phosphoric acid, and then AC was used for the simultaneous adsorption of diuron and 3,4-dichloroaniline in water. It was characterized by SEM, FT-IR and BET. The results showed that AC possessed oxygen-containing functional groups and abundant pore structure, and its specific surface area 947.96 m^(2)/g. The activated carbon was added in an amount of 4 mg, and it showed an adsorption capacity of 70.66 mg/g and 64.90 mg/g for diuron and 3,4-dichloroaniline.The adsorption of diuron and 3,4-dichloroaniline fitted to the kinetics accords with the pseudo-second-order model and the Langmuir model.
