Efficiency of recycled wool-based nonwoven material for the removal of oils from water 总被引:4,自引:0,他引:4
The aim of this study was to highlight the potential use of recycled wool-based nonwoven material for the removal of diesel fuel, crude, base, vegetable and motor oil from water. Sorption capacity of the material in water and in oil without water, oil retention, sorbent reusability and buoyancy in static and dynamic conditions were investigated. The results show high sorption capacity of recycled wool for different kinds of oil. This sorbent also exhibited excellent buoyancy after 24h of sorption as well as a good reusability since the decrease in sorption capacity did not exceed 50% of the initial value after five sorption cycles in oil without water. 相似文献

Ion exchange materials that are highly selective for ammonia have been used for wastewater treatment but they are mainly suitable for use in non-saline water. In this paper, some new materials have been evaluated for the selective uptake of ammonia from saline wastewater. Those materials include: MN 500 (belongs to the group of material known as Macronets which are hypercrosslinked polyvinyl styrenes) as well as some chemically modified zeolites and products of zeolite nature. Equilibrium isotherms for ammonium ion uptake determined in a series of shake flask experiments using materials exposed to varying concentrations of ammonium ion in artificial seawater are shown. Capacity and selectivity data for these materials for ammonium ion are also presented. 相似文献
