【摘要】 本文在研究醛类化合物与尿素反应的基础上,确定含有α—羰醛基的化合物在pH7.4,37℃下对尿素有较高的反应活性。将α—羰醛基引入到苯乙烯—二乙烯苯共聚物骨架上,合成出带有α—羰醛基的树脂。实验结果表明,含α—羰醛功能基的树脂在pH7.4,37℃条件下与目前临床使用的氧化淀粉相比,具有更大的吸附潜力。本文还研究了吸附条件对该树脂吸附性能的影响。更多还原

【Abstract】 The α- Keto - aldehyde group bound polymer of polystyrene - divinyl benzene was prepared and its adsorption for urea was studied in this work. It is confirmed that the polymer bound α-Keto-aldehyde group shows higher reaction activity to urea than the one containing only the aldehyde group in pH 7. 4 at 37℃.更多还原
