| 摘要： | Poplars produce quantities of leaves during their growth, which are usually burned or deserted directly. In this study, the deciduous leaves were reclaimed and made into organic granules. During the granulation, the adsorption capacity was not obviously depressed compared with leaf powder, but the granules were more convenient to be separated from the solution after saturation. Being made under relatively low temperature of 378K, this material maintained the natural structure and ingredients of poplar leaves and supplied quantities of nanolevel structures in the cell wall and other cellular parts. The application of the granules in nitrobenzene removal indicated that this material was efficient in nitrobenzene adsorption from water. The adsorption was spontaneous under normal room temperature and neutral pH, which made it more competent than other adsorbents. The adsorption of nitrobenzene onto the granules complied well with the pseudo-second-order model and Langmuir isotherm model. |
