一種類芬頓預處理試劑，利用低濃度氯化鐵和過氧化氫在混合溶劑下，對玉米桿進行預處理。預處理後溶液中可得到可溶性單醣與低聚物可溶性糖類，預處理的芬頓試劑以及有機溶劑對環境影響較小，預處理條件是在溫和的條件下進行。另外試劑中的金屬鹽可以用四氧化三鐵代替氯化鐵，四氧化三鐵具有磁性可以利用強力磁鐵回收預處理後的四氧化三鐵，減少金屬鹽類含量。;A Fenton-like pretreatment reagent be developed that pretreated the cornstalk with a low concentration of FeCl3 and H2O2 in a mixed solvent system. Soluble monosaccharides and oligomer were obtained in the solution after pretreatment, and the pretreated reagent and organic solvent have low effect to the environment. In addition, the metal salt (FeCl3) in reagent can be replaced by Fe3O4. Fe3O4 has magnetic properties. The pretreated Fe3O4 can be recovered by a powerful magnet to reduce the metal salt content.
