以蔗渣纤维素为研究对象，通过分析环氧氯丙烷用量、反应温度和反应时间对蔗渣纤维素环氧值的影响，确定蔗渣改性的较优条件。结果表明，当环氧氯丙烷与蔗渣纤维素用量（V/m）为4:1、反应温度为50 ℃、反应时间为5 h时，环氧值最高。在此条件下改性后的蔗渣纤维素对糖蜜中的色素有较好的吸附功能，脱色率达到25.59%。

[Abstract]
The effects of epichlorohydrin amount, reaction temperature and reaction time on epoxy value of bagasse cellulose were investigated. Result showed that the epoxy value reached the highest when epichlorohydrin amount-bagasse cellulose ratio, reaction temperature and reaction time were 4:1 (V/m), 50 ℃ and 5 hours, respectively. At the same time, the modified bagasse cellulose had a better adsorption on molasses, with the decoloration rate being of 25.59%.
