碳納米管的羧基化 測定羧基含量 酸堿滴定
|
| 在用硫酸和硝酸的混酸處理了碳納米管之后,期望碳納米管上面被氧化連接上羧基,那么為了測量羧基的含量用酸堿滴定法的話該如何操作呢?一篇文獻上這么說:The modified CNT materialwas quantitatively analyzed by titration to determine the COOH concentrations on the surface of the treated CNTs. In a typical experiment, the carboxylated CNTs were added into a 25-ml 0.04 N NaOH solution and stirred for 48 h to allow the solid CNT material to equilibrate with the NaOH solution. The mixturewas titrated with a 0.04 N HCl solution to determine the excess NaOH in the solution and the concentration of the carboxylates on CNTs. |
