请问这篇文献中他是怎么把PH调节到9.5的,直接用水稀释吗,还是加酸?The mixed MnOx-CeO2 binary oxide catalysts were prepared by coprecipitation involving the surfactant cetyltrimethyl-ammonium bromide (CTAB) in the process. Take the sample with a Mn/Ce ratio of 5:5 as an example: 0.01 mol of Mn(CH3COO)2 ·4H2O and 0.01 mol ofCe(NO3)3 ·6H2O were simultaneously dissolved in 150 mL of distilled H2O, and 0.008 mol of CTAB was dissolved in 100 mL of distilled H2O. Then, the two kinds of solutions were mixed under stirring, giving a clear homogeneous solution, which was continuously stirred for 2 h. Afterward, about 30 mL of 2 M NaOH solution was quickly added under vigorous stirring to form a solid precipitate. The pH was adjusted toaround 9.5.请问这篇文献中他是怎么把PH调节到9.5的,直接用水稀释吗,还是加酸?查看更多7个回答 . 26人已关注
英文看不懂,请赐教!?the embedded ionic liquid was removed from the silica by extracting the samplewith methanol in an extraction and stripping apparatus at 65 C for3 days。 弱弱问一下in an extraction and stripping apparatus??是什么意思呢? 请赐教!查看更多5个回答 . 7人已关注
