可见峰位大致相同,在3600 cm-1左右较强地吸收峰,其对应的是AI

It can be seen that the peak positions are roughly the same, with a strong absorption peak around 3600 cm-1, which corresponds to the stretching vibration peak of AI-OH. The broad peak at about 3400 cm-1 is the absorption peak of hydroxyl stretching vibration of water in bentonite after treatment, and the strong absorption peak at 1630 cm-1 is also the absorption peak of water. The absorption peaks at 1035 and 800 cm-1 correspond to the inverse stretching vibration of silica. However, there is a hydrocarbon stretching vibration peak at 2987 cm-1, which does not appear on the bentonite treated with water, which proves that a small amount of plugging material is adsorbed on the surface of the bentonite, further confirming the XRD analysis results.

The visible peak level is approximately the same, with a strong absorption peak around 3600 cm-1, which corresponds to the telescopic vibration peak of AI-O-H. The corresponding wide peak of about 3400 cm-1 is the hydroxyl telescopic vibration absorption peak of water in the treated bentonite soil, and the strong absorption peak at 1630 cm-1 is the same as the absorption peak of water. The absorption peaks at 1035 and 800 cm-1 correspond to the anti-telescopic vibration of silicon dioxide. At 2987 cm-1, a telescopic vibration peak of hydrocarbon appeared, which did not appear on the water-treated bentonite, proving that a small amount of sealing material adsorption on the puffed soil surface further confirmed the XRD's analysis results.

It is found that the peak position is almost the same, and the peak is strongly absorbed at 3600 cm-1, which corresponds to the expansion vibration peak of ai-o-h. The corresponding broad peak of 3400 cm-1 is the peak of Hydroelastic vibration absorption of the treated bentonite, and the stronger absorption peak at 1630 cm-1 is the same as that of water. The absorption peaks at 1035 and 800 cm-1 correspond to the anti expansion vibration of silica. However, the peak of hydrocarbon expansion vibration appeared at 2987 cm-1, which did not appear on the bentonite treated by water. It was proved that a small amount of plugging materials adsorbed on the surface of bentonite, further confirmed the XRD analysis results.<br>
