The effect of 5-MeV electron accelerator irradiation of 400 kGy on the formic acid cycling separation of cellulose, lignin, and xylose from Triarrhena lutarioriparia (TL) were studied, and the enzymatic conversion rate and structural characteristics of TL cellulose were analyzed. For 400 kGy irradiated TL, the results revealed that the average purity of cellulose was 81.13% and the recovery of lignin and xylose were 28.68% and 10.16%, respectively, which were higher than those of the unirradiated sample. The recovery of cellulose, concentration...
