Summary: | In this paper, a macroporous cellulose resin (toluene diisocyanate crosslinked cellulose, TCC) was prepared by using toluene diisocyanate crosslinking agent. Analyses of Fourier transform IR spectra confirmed a successful crosslinkage. Chemical shifts of 13C nuclear magnetic resonance of TCC also proved the chemical structure. TCC was observed by scanning electron microscopy, and the images showed porous characteristics and increased surface area. Based on the strong polarity of TCC, rutin was used to check static adsorption and desorption capabilities. The adsorption isotherms of TCC as well as commercial D101 and AB‐8 macroporous resin were compared and explained using the Freundlich equation. Dynamic adsorption was also examined, and the influence of feed flow rate and pH value on the breakthrough volume are discussed. The dynamic desorption of rutin from TCC was carried out and the influence of eluent concentration (ethanol concentration) on desorption rate was analysed. The results of adsorption and desorption of rutin revealed that TCC is a potential tool for separating strong polar organics especially flavone glycosides from plants. Based on the detection of cellulosic bacteria, TCC is superior to commercial macroporous resins in biodegradability. Copyright © 2012 Society of Chemical Industry
Biodegradable macroporous resin prepared by crossing cellulose with TDI exhibits better adsorption and desorption effect on rutin. |
