【求助】关于H2O2的干燥问题
|
||
|
The MWNT was treated by H2O2 with an aid of the sonication. The 1.0 g MWNT was treated with the 400 ml of H2O2 at 50 C for 90 min. The treated MWNT and H2O2 mixture was dried by two different methods: (i) thermal drying, which is the MWNT and H2O2 mixture was dried for 12 h at 80 in the drying oven.(ii) Freeze drying, which is the MWNT and H2O2 mixture was centrifuged for 1 h, then the mixture was washed with distilled water until the MWNT and H2O2 mixture contained almost no acidity (pH 6.0–6.5). Then, the MWNT and H2O2 mixture was freeze dried at K60 C for 72 h. 我是新手，请问大家我想用第一种方法，但是不知道是不是可以直接把超声分散后的双氧水溶液直接放在真空干燥箱里面烘干，会不会爆炸？谢谢大家了！ |
