| 제목 | Removal of nitrates using amine grafted and magnetized SBA-15 |
| 초록 | To remove nitrates from water bodies, SBA-15 has been used. However, its adsorption capacity for nitrates is not so high because of its chemical stability. And its reusability is also an important factor. To overcome these limitations, the SBA-15 has been modified such as amine-grafting and magnetization. In general, APTES, aminopropyltriethoxysilane, has been used as a grafting material to overcome low adsorption ability for nitrates. In many references, 16 mmol of APTES was used to enhance the adsorption capacity. But in this work, various amounts of APTES were tried to find the best amount of the grafting agent. The magnetization of SBA-15 was also carried out by introducing 0.5 g of SBA-15 and various amounts of Fe(NO3)3∙9H2O. And then the best magnetized SBA-15 was grafted using the best amount of APTES. It was proven that the grafted and magnetized SBA-15 sample has not only a good recyclability but also high adsorption capacity to remove and recover nitrates from water streams. |
