| The FTIR spectra of _-CD and the resin are shown in Fig. 2. The strong and wide OH peak for _-CD at 3404 cm−1 moved toward a lower wave number, and the resin had a strong and broad absorption peak at 3363 cm−1 (Ficarra et al., 2002). The introduction of acrylic acid increased OH, which led to the shift of the OH peak toward a lower wave number. Furthermore, the OH group absorption peak became broader because of the increasing hydrogen bonding between molecules. The CH2 stretching vibrations at 2925 cm−1 and 2846 cm−1 were significantly increase for the resin, which is mainly due to the formation of CH2 in the polymerization process during the introduction of acrylic acid and acrylamide monomer. Strong overlapping peaks at 1671 cm−1 can be attributed to C O stretching vibration peaks in acrylamide and carboxylic acids (Kuang, YuK, & Huh, 2011). |

| β-CD和樹脂的傅立葉變換紅外（FTIR）光譜見圖2。β-CD在3404厘米-1的強而寬的OH峰移向低波數(shù)，而樹脂強而寬的吸收峰在3363 cm-1處（Ficarra等人，2002）。丙烯酸的引入增加了OH，導致OH吸收峰位移向低波數(shù)。另外，OH基吸收峰因為分子間氫鍵的增加變得更寬。樹脂的CH2的伸縮振動在2925 cm-1和2846 cm-1明顯增加，這主要是由于在引入丙烯酸和丙烯酰胺單體的聚合過程中形成了CH2。在1671 cm-1處強疊嶂可以歸結(jié)為在丙烯酰胺和羧酸中CO的伸縮振動峰（Kuang, YuK, & Huh, 2011）。 |
