摘要 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%。 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%.
