【摘要】 本文以甘蔗渣纤维素为原料,碱化后,以脲为催化剂,与磷酸作用,研究甘庶渣纤维素磷酸酯的最佳工艺条件,并对产品结构进行初步表征。实验表明产品的交换吸附性能优于一般活性碳,并且对重金属离子有一定的吸附和选择性交换性能。更多还原

【Abstract】 Sugarcane cellulose phosphates can be synthesized by using alkali-cellulose reacts with phosphoric acid catalyzed by urea. The best synthesis techincal condition was studied, and the structure of the ester was characterized initially. The experi-ment result shows that its exchange adsorption capacity is better than the normal active carbon, and it can selectively adsorb some weigh mental cation.更多还原
