采用山竹壳为原料制得山竹壳基生物质活性炭。确定了较佳的制备条件:在尿素酸溶液∶碳=1∶1(质量比)的浸渍比下,浸渍时间15h,活化温度750℃,活化时间60min,制得的山竹壳基生物质活性炭比表面积为545.68m2/g。在亚甲基蓝溶液pH=4.5、初始浓度为25mg/L,山竹壳基生物质活性炭用量为0.06g条件下,山竹壳基生物质活性炭对亚甲基蓝的吸附量达到68.75mg/g。
Mangosteen shells were chosen as raw materials for preparing novel activated carbon.The preferred preparation conditions were as follows:the impregnation time of 15h,activation temperature of 750℃,activation time of 1h and Impregnation ratio of 1∶1.The specific surface area could reach 545.68m2/g.The factors affecting adsorption experiments,including pH=4.5,dosage of activated carbon=0.06g,and initial concentration=25mg/L were also studied and the adsorption properties were characterized by methylene blue adsorption experiments which the adsorbance was 68.75mg/g.
