【摘要】 基于Washburn方程用亲油亲水比(LHR)比较了无烟煤、沸石和石英砂滤料对油的润湿选择性,并对其表面结构进行了表征.结果表明,无烟煤、沸石和石英砂的LHR值依次为2.41、0.64和0.65,沸石和石英砂的亲水性明显好于无烟煤,而无烟煤的亲油性好于沸石和石英砂.这主要取决于滤料的表面化学组成,同时与其表面形貌有一定的关系,与SEM、XPS、FTIR分析结果基本吻合.
【英文摘要】 The oil-wetting selectivity of anthracite,zeolite and quartz sand filtration media was compared with lipophile hydrophile ratio(LHR)based on Washburn equation,and their surface structure was expressed.The hydrophilism of zeolite and quartz were better obviously than anthracite,while the lipophilism was better than the zeolite and quartz.The calculated LHR values of anthracite,zeolite and quartz sand were 2.41,0.64 and 0.65,respectively,showing that the anthracite wet selectivity on oil was good,while that o...
