摘要:
采用琥珀酸溶液活化法制备改性水稻秸秆,利用扫描电子显微镜(scanning electron microscope,简称SEM)和傅里叶红外光谱仪(Fourier transform infrared spectrometer,简称FT-IR)对改性前后样品的组成、形貌进行表征,对比了秸秆改性前后的结构和成分变化。采用静态吸附试验,研究初始pH值、吸附剂添加量和吸附时间对二价镉 Cd(Ⅱ) 吸附性能的影响。结果表明,改性后水稻秸秆形貌无明显变化,但组成成分有一定变化,其中羧基数量增加。在一定范围内增大改性水稻秸秆用量、溶液pH值和吸附时间有助于提高改性水稻秸秆对Cd(Ⅱ)的吸附量,吸附动力学可用拟二级动力学方程描述,等温吸附模型符合Langmuir方程。
