MO和吸附反应前后吸附剂的红外光谱全谱图及细节图被展示在图6。红外数据

The full spectrum and details of the infrared spectrum of the MO and the adsorbent before and after the adsorption reaction are shown in Figure 6. The infrared data shows the characteristic absorption peaks of the functional groups on the MO molecule used in the experiment: the broad and strong peak at 1189.8 is the absorption peak of the sulfonate functional group; 1606.4, 1519.6, and 1443.6 are the vibrational absorption peaks of the benzene ring skeleton, and 847.6 and 817.7 are the MO molecules The out-of-plane deformation vibration absorption peaks of CH on the two benzene rings in the two benzene rings; the characteristic absorption peaks of CH3 appear at 2901.4, 2817.2, and 1366.1 (its absorption peak wave number is less than the ordinary CH3 absorption peak wave number, because CH3 and N in the MO molecule The atoms are connected, and the CH3 absorption peak of MO shifts to the low wavenumber direction) [42] [43]. Both HNTs and ChNTs belong to layered silicate minerals. One strong and one weak two absorption peaks in the range of 3690-3630 are the OH stretching vibration absorption peaks of the layered silicate, and about 960cm is the strongest stretching of Si-O. Vibration absorption peak [44].

The infrared spectral full spectrum and detail map of mo and adsorption reactions before and after adsorbents are shown in Figure 6. Infrared data show the absorption characteristic peak of the MO molecular energy group used in the experiment: 1189.8 wide and strong peak is the absorption peak of sulfonate official group; Benzene ring skeleton vibration absorption peak, 847.6, 817.7 is the MO molecule on the two benzene ring C-H surface deformation vibration absorption peak; 1366.1 (the number of absorbed peak waves is less than the number of normal CH3 absorption peak waves, because in the MO molecule CH3 is connected to the N atom, there is a MOVEMENT of MO's CH3 absorption peak in the direction of low wave count). HNTs and ChNTs belong to the layered silicate mineral, 3690 to 3630 range of one strong one weak two absorption peaks are layered silicate OH telescopic vibration absorption peak, 960cm or so is its Si-O's strongest telescopic vibration absorption peak.

The infrared spectra of Mo and the adsorbent before and after the adsorption reaction are shown in Fig. 6. The infrared data show that the absorption characteristic peaks of functional groups on Mo molecule used in the experiment are as follows: the broad and strong peaks at 1189.8 are the absorption peaks of sulfonate functional groups; 1606.4, 1519.6, 1443.6 847.6 and 817.7 are the out of plane deformation vibration absorption peaks of C-H on two benzene rings in Mo molecule; the characteristic absorption peaks of CH3 appear at 2901.4, 2817.2 and 1366.1 (the wave number of the absorption peak is less than that of ordinary CH3, which is because CH3 is connected with N atom in Mo molecule, and the CH3 absorption peak of Mo moves towards low wave number) [42] [43]. HNTs and chnts belong to layered silicate minerals. In the range of 3690 ~ 3630, one strong and one weak absorption peak is the stretching vibration absorption peak of Oh in layered silicate, and 960cm is the strongest stretching vibration absorption peak of Si-O [44].<br>
