| 摘 要： | 以杉木屑为原料,采用磷酸浸渍在高温下对其进行活化,制备活性炭。探讨温度、保温时间、磷酸浓度对活性炭性能的影响。结果表明,随着温度和保温时间的增加,活性炭的亚甲基蓝吸附值、碘吸附值和苯吸附值总体呈上升的趋势。随着磷酸浓度的增加,活性炭的亚甲基蓝吸附值和碘吸附值呈先降后升的趋势。在较优的实验工艺下,活性炭的亚甲基蓝吸附值、碘吸附值和吸苯率分别为330.0 mg·g-1、1 015.7 mg·g-1和59.2%。

| Abstract: | To prepare activated carbon,sawdust was impregnated in phosphoric acid,then activated in high temperature.The main parameters such as temperature,holding time and the concentration were studied to show the effect on the adsorption capabilities of the activated carbon.It was found that with the increase of temperature and holding time,methylene blue,iodine,benzene adsorption values of activated carbon showed overall upward trend.With the increase of the concentration of phosphoric acid,the methylene blue and... |
