【摘要】 通过测定不同活性炭的比表面积,和它们的荧光显微微观结构分析,以及它们对水体中常见的黄腐酸和苯酚两种不同分子大小的有机物吸附性能比较得知,活性炭对有机物的吸附量的大小不仅与其比表面积大小有关,而且还与它们的微孔结构大小和有机物分子结构的大小有直接的关系,为粉末活性炭在饮用水处理的应用提供一定的指导依据。更多还原

【Abstract】 The specific surface area, the fluorescence microstructure of Shanghai woodiness active carbon, Fujian woodiness active carbon, Maoming woodiness carbon and Shanxi coal active carbon were analyzed, and the adsorption capability for two kinds of organics with different molecular weight was compared. The results indicated that the adsorption capability was not only related to the specific surface area, but also related to the micro-pore of the active carbon and the size of organic compounds. And the results would be a guiding foundation for the powder active carbon applied in drinking water treatment.更多还原
