中文：為了進(jìn)一步研究吸附機(jī)理，測定了吸附前后AAA的紅外光譜，如圖6-9所示。AAA紅外吸收峰并不明顯。IBP和SMX曲線表明，3417和3400 cm-1寬而強(qiáng)的吸收峰為-OH伸縮振動峰。1535和1600 cm-1為芳環(huán)C=C骨架伸縮振動峰，1137 cm-1為C-N伸縮振動峰。730 cm-1為C-H變形振動峰。吸附IBP后，AAA分別出現(xiàn)了三個新峰，分別為在3334 cm-1處的-OH伸縮振動，1608 cm-1處的芳環(huán)C=C骨架伸縮振動，584 cm-1處的Fe的特征峰。上述結(jié)果充分表明，IBP已成功被AAA吸附。同樣，AAA吸附SMX也展現(xiàn)出類似的特征和機(jī)理。 英文：To further study the adsorption mechanism, the infrared spectra of AAA were detected before and after adsorption of IBP and SMX, as shown in Figure 9. The infrared absorption peak of AAA is not obvious. A type of the IBP and SMX curves that shows the broad and intense absorption peaks around 3417 cm-1 and 3400 cm-1 can be attributed to the -OH stretching vibration. The absorption bands at 1535 cm-1 and 1600 cm-1 are assigned to skeleton stretching vibration of C=C bond in aromatic ring. The absorption bands at 1137 cm-1 and 730 cm-1 are attributed to stretching vibration of C-N bond and deformation vibration of C-H bond, respectively. After adsorption of IBP, there are three new peaks in AAA, namely -OH stretching vibration peak at 3334 cm-1, aromatic ring C=C skeleton stretching vibration peak at 1608 cm-1 and Fe characteristic peak at 584 cm-1. The above results fully indicate that IBP has been successfully adsorbed by AAA. Similarly, the adsorption of SMX by AAA exhibits similar characteristics and mechanisms. |
