| 摘 要： | 酸性亚硫酸盐处理木质纤维素产生的废液含有木素磺酸盐、糠醛和羟甲基糠醛(HMF)等生物抑制剂,快速、同步测定这些物质对于生物质精炼具有重要意义.本文建立了衰减全反射( ATR) -UV光谱法用以快速、同步测定亚硫酸盐废液中三种生物抑制剂的浓度.使用单波长和双波长校正可以测定木素磺酸盐的浓度,这两种方法得到的数据非常接近....

| Abstract: | The effluent from eucalyptus pretreated by acidic sulfite contains lignosulfonates,furfural and hydroxymethyl furfural(HMF).It is important for biomass refining to determine these bio-inhi-bitors accurately and rapidly.In this paper,attenuated total reflection ultraviolet(ATR-UV) spectroscopic method was developed for determination of concentration of three bio-inhibitors in effluent from eucalyptus rapidly and simultaneously.The single-wavelength and dual-wavelength calibration can be used for determinatio... |
