摘　　要：以含有丰富的纤维素和半纤维素的废弃枯叶作为基体,用特定改性方法接枝季胺基官能团,制备季胺基改性废弃枯叶水处理吸附材料。采用SEM、FTIR等表征手段分析所制备材料的形貌及官能团,并以水中NO3-N为对象,探究改性废弃枯叶吸附剂材料的最佳组合条件。结果表明:采用改性油桐树叶,在反应条件为15 min下,投加量为0.05 g,反应温度为28℃下,对NO3-N去除率可高达87.67%。Waste dead leaves were used as the matrix,which contained abundant cellulose and hemicellulose.Quaternary amine groups were grafted by specif ic modif ication method to prepare quaternary amine modif ied waste dead leaves water treatment adsorption materials.SEM,FTIR and other characterization methods were used to analyze the morphology and functional groups of the prepared materials.Taking NO3-N in water as the object,the optimal combination conditions of modif ied waste dead leaf adsorbent materials were explored.The results showed that the removal rate of modif ied tung oil tree leaves could reach 87.67%under the reaction conditions of 15 min,0.05g dosage and 28℃.
