中文：为了进一步研究吸附机理，测定了吸附前后AAA的红外光谱，如图6-9所示。AAA红外吸收峰并不明显。IBP和SMX曲线表明，3417和3400 cm-1宽而强的吸收峰为-OH伸缩振动峰。1535和1600 cm-1为芳环C=C骨架伸缩振动峰，1137 cm-1为C-N伸缩振动峰。730 cm-1为C-H变形振动峰。吸附IBP后，AAA分别出现了三个新峰，分别为在3334 cm-1处的-OH伸缩振动，1608 cm-1处的芳环C=C骨架伸缩振动，584 cm-1处的Fe的特征峰。上述结果充分表明，IBP已成功被AAA吸附。同样，AAA吸附SMX也展现出类似的特征和机理。 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. |
