  • 摘要: 利用尿素溶液氨化改性小麦秸秆,通过扫描电镜和傅里叶变换红外光谱观察其改性前后的表征,研究不同初始pH与投加浓度对改性前后小麦秸秆吸附水溶液中Cd 2+的效果,并通过动力学与热力学模型拟合小麦秸秆的吸附动力学与等温吸附特征。结果表明:氨化改性小麦秸秆的结构疏松,孔隙增大,表面嫁接了伯酰胺基团,各官能团活性增强,有利于提高对Cd 2+的吸附能力;氨化改性小麦秸秆吸附Cd 2+的最适宜条件是pH为6、温度为25 ℃、吸附剂投加浓度为1/300 g/mL,此条件时对Cd 2+的吸附率达74.32%,最大饱和吸附量为11.29 mg/g;不同温度下,氨化改性小麦秸秆对Cd 2+的吸附可用准二级动力学方程描述,表现为吸热反应;对Cd 2+的吸附热力学过程可用Langmuir模型描述,表现为以化学吸附为主。
