摘　要:研究了用聚四氟乙烯纤维为滤料处理含油污水时的吸附和脱附特性。测定了滤料的吸附等温线,以及温度、pH对吸附性能的的影响。分析了纤维表面的形貌特征和吸附机理。常温下PTFE吸附油污90 min后达到吸附平衡;当温度=50℃、pH=3时吸附量最大,可达42.26 mg/g。[著者文摘]

Adsorption/desorption Behaviors of Oil Pollutants on Polytetrafluoroethylene and Their MechanismYANG Jing, ZENG Fan-long, REN Qing-chun, CAO Qian-zhi 1. State Key Lab. For chemical fibers modification and polymer material, college of material Sci.＆Eng., Donghua University, Shanghai 201620, China; 2. Beijing Linisplendour Empyrerl Environmental Eng. Tech.Co., Beijing 100083, ChinaAbstract:Application of Polytetrafluoroethylene（PTFE） in treating oily wastewater by fiber filter was studied.The adsorption isothermal curve was researched as well as influence of temperature and pH on adsorptivity.The characteristic of fiber surface and adsorption mechanism were analyzed.The results show that the maximum amount of adsorption is 42.39 mg/g at the temperature of 50 ℃,pH of 3 and adsorption time of 90 min.[著者文摘]
