Abstract

Cellulose obtained from rice straw was grafted with polyvinylpyrrolidone (Cell-g-PVP). The process was induced by simultaneous gamma iradiation (Co-60). The presence of the grafted PVP chains was confirmed by FT-IR, XRD and EDS methods. The influence of the iradiation dose (20 and 30 kGy) on the reaction efficiency and thermal stability of Cell-g-PVP was investigated. The grafting yield at the dose of 30 kGy was about 56%. The higher dose of radiation resulted in better thermal stability. The AAS results showed that Ni(II), Cu(II), and Cr(II) ions can be adsorbed by Cell-g-PVP. The order of ion metals adsorption capacity of Cell-g-PVP was Cu(II) > Ni(II) > Cr(II). The adsorption isotherm of Cu(II) metal ion using the Cell-g-PVP followed the Langmuir adsorption isotherm whereas the chemical adsorption and the adsorption energy were constant on all sides of the copolymer.

γ诱导聚乙烯吡咯烷酮接枝稻草纤维素

以稻草为原料，用聚乙烯吡咯烷酮（Cell-g-PVP）接枝纤维素。该过程是由同时γ射线辐照（Co-60）诱导的。通过FT-IR、XRD和EDS等方法证实了接枝PVP链的存在。研究了辐照剂量（20和30kGy）对Cell-g-PVP反应效率和热稳定性的影响。30kGy剂量的接枝率约为56%。辐射剂量越高，热稳定性越好。原子吸收光谱结果表明，Cell-g-PVP可以吸附Ni（II）、Cu（II）和Cr（II）离子。Cell-g-PVP对离子金属的吸附能力依次为Cu（II）>Ni（II）>Cr（II）。使用Cell-g-PVP对Cu（II）金属离子的吸附等温线遵循Langmuir吸附等温线，而化学吸附和吸附能在共聚物的所有侧面上都是恒定的。
