| 摘 要： | 以甘蔗渣为原料,用丙烯腈和盐酸羟胺对其进行改性,在甘蔗渣分子中引入胺肟基团,提高其对金属离子的吸附能力.讨论了羟胺化反应条件如温度、时间、羟胺质量浓度对胺肟基团含量的影响.用红外光谱表征了产物的结构,用元素分析法测试了产物中氮元素的含量.在反应温度90℃、反应时间180min、羟胺质量浓度100g/L时,改性甘蔗渣中最大含氮元素为13.4%,最大含胺肟基团为3.38mmol/g,并对改性产物进行了铜离子的吸附研究,其最大铜离子吸附量为54.0mg/g.

| Abstract: | Bagasse-based ion adsorbents were prepared by successive reactions of bagasse with acrylonitrile in an alkaline medium followed by aqueous hydroxylamine to prepare amidoximated bagasse with the aim to enhance the ability to remove heavy metal ions from waste water. The structure of the modified materials was characterized using Fourier Transform Infrared (FT-IR). The content of nitrogen in modified bagasse was determined by elemental analysis. The effect of experimental parameters, namely, reaction time, te... |
