  • 摘要: 以长柄扁桃核壳为原料采用磷酸活化法制备活性炭，分别研究了温度、时间、浸渍比和磷酸浓度对活性炭吸附性能的影响；进而采用氮气吸附曲线和SEM对最佳工艺条件下的活性炭进行了表征。结果表明，长柄扁桃核壳是一种优质的活性炭原料；当温度为400℃，活化时间2 h，浸渍比2：1，磷酸浓度60%时，得到产率为46.46%，碘吸附值和亚甲基蓝吸附值分别为1 073 mg/g、255 mg/g，比表面积高达1 740 m2/g，中孔率为73.12%的孔隙发达的高中孔率活性炭。
    Abstract: Activated carbon was prepared from amydalus shell through phosphoric acid activation. This paper discusses the effect of factors,including temperature,time,the ratio of impregnation and solution concentration on the adsorption capacity of the activated carbon,and characterizes it which derived from the optimum conditions by nitrogen adsorption-desorption isotherms and SEM. The results show that the amygdalus shell is a good raw material of activated carbon and the optimum conditions are as follows:activation temperature of 400℃,activation time of 2 h, ratio of 2:1 and phosphoric acid concentration of 60%. Under the above conditions,high mesoporous activated carbon was made,whose iodine adsorption,methylene blue adsorption,specific surface area,mesopore rate,yield were 1 073 mg/g,255 mg/g,1 740 m2/g,73.12% and 46.46%, respectively.
