Wheat straw (WS) was oxidized in a sodium hypochlorite (NaOCl) aqueous solution at 40°C followed by sequential extraction of the water-soluble fraction (WSF) with petroleum ether, carbon disulfide (CDS), diethyl ether and ethyl acetate (EA). The EA-inextractable solution was acidized and filtrated. The filtration was also sequentially extracted with the same series of solvents. In total, 38 organonitrogen...
High-silica zeolites (US-Y and ZSM-5) were used to adsorb organics from retort waters derived from Stuart oil shale (Queensland, Australia). Removal of organics increased with decreasing polarity of the adsorbate and improved when free ammonia was removed first by air stripping. Zeolites were more effective than activated carbon. They are easily regenerated and are potential agents for pretreatment...
