摘要
Abstract
Fir powder was dissolved in ionic liquid of 1-(2-hydroxylethyl)-3-ethyl imidazolium chloride ([HeEIM]Cl) by microwave heating (400 W, 90℃), then acrylamide (AM) was grafted onto the dissolved wood with initiator of K2S2O8 in the dissolution system to prepare the graft copolymer AM-g-wood, which was a novel modified flocculant. The chemical structure and crystalline structure of the flocculant were determined by FTIR and XRD respectively. The effects of ionic liquid and aqueous medium on graft copolymerization were studied. The flocculation properties of AM-g-wood on coal slurry water and argil wastewater were investigated. The results of FTIR and XRD showed that graft copolymerization occurred between AM and fir powder. The performance of AM-g-wood prepared in ionic liquid medium was far superior to that prepared in aqueous medium, and the graft copolymer was more suitable for treating argil wastewater with tiny particles. The effect of flocculation was better when inorganic flocculant of poly aluminum chloride (PAC) was used as synergistic agent.关键词
