Preparation, Characterization and Dye Decolorization Application of Chitosan/Polyurethane Foam Material

摘要

A series of chitosan/polyurethane (Cs/PU) materials were prepared from polyether polyol, isophorone diisocyanate, chitosan, n-hexane as foaming agent, dibutylbis (lauroyloxy) tin as catalyst and silicon oil as stabilizer by foaming technique. The materials were characterized by FT-IR, DSC and TGA. Cs/PU materials were used to decolorize azo dye. Decolorizing process was spontaneous at ambient temperature and presented an exothermic characteristic. The decolorization experiments were carried out and around 78% of the azo present in solution could be removed. The experimental results suggest that the Cs/PU materials have potential applications as decolorizing agent for the treatment of dye effluents.View full textDownload full textKeywordsChitosan, Decolorization, Foam material, PolyurethaneRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/03602559.2012.663044
