[求助] FTIR一段话,改写,请大家帮助。散全部金币了。多谢多谢

中文:A谱图中1700cm处酯化羧基官能团-COOCH3的C=O振动峰在B谱图中显著减弱,这说明改性过程中吸附剂在碱作用下伴随着纤维溶胀发生酯水解的过程。C谱图中1714cm出现的新峰可能是巯基乙酸与吸附剂主链接枝生成巯基乙酸酯的变化。D谱图中,巯基酯峰消失可能是由于硫化铜分子的生成。醚键1037cm红移到1053cm、1600cm骨架峰红移到1637cm, 同样也可说明纤维素结构的转变和在肌层内部生成分子态硫化铜的过程。这种高分散的活性硫化铜可解释改性吸附剂吸附Cr(III)和Cr(VI)高效能的机理。
晰晰最棒,晰晰加油,让我们变得更富有,生活变得更加美丽。

Referring to Spectrums A and B, it can be seen that the intensity of the peak at 1700cm-1, the one attributed to the vibration peak of C=O group in the esterified carboxy group -COOCH3, was drastically weakened from Spectrum A to Spectrum B, indicating that, in the presence of a base, the adsorbent was subjected to esterolysis as the fiber was swelled during modification. Additionally, a new peak at 1714cm present in Spectrum C might be attributed to the formation of mercaptoacetate by grafting the thioglycollic acid to the main chain of the adsorbent. Furthermore, in Spectrum D, the peak of mercaptoacetate was disappeared, indicating the formation of CuS molecules. The peak of the ether bond was red-shifted from 1037 to 1053, while the peak of the backbone was red-shifted from 1600 to 1637. Such red-shifts also demonstrated the changes of the cellulose structures and the formation of molecular CuS within the muscular layer. The well-dispersed active CuS could be contributed to the high efficiency of the modified adsorbent to absorb the Cr(III) and Cr(VI).

红外单位可能是波数,还需楼主再确认一下。
祝楼主早日顺利毕业!
