A稍有溶胀；B显示清晰溶胀，纤维间产生裂隙，增大了交换和螯合面积。C溶胀最为显著，表面增加明显，纤维内部产生孔道，为提高交换络合能力提供了结构基础。这是由于OA链短，酸性最强，CA 为5碳链三羧酸，产生的内孔道最弱。 注：纤维素经酸洗后生成三个产物A，B和C。SEM图片解析 |

| The SEC images of acid modified cellulose derivatives show that A has only a slight swelling; B shows a clear swelling, and cracks between fibers are visible, which increases the work surface for ion exchange and chelation; C shows the most extensive swelling, with obviously increased porosity within fibers(多孔结构存在时载面积可以忽略不计了), which provides the structural basis for the biggest improvement in ion exchange and chelation capacity. This is because the OA chain is short and has the strongest acidity, while CA is a tri-carboxylic acid with 5 carbon units spacing , which makes the inner channel the weakest degree of ionization. |
