Abstract

Preparation of magnetic chitosan for mercury removal from polluted water had been conducted. Magnetic particles (FeO) were isolated from local iron sand to provide magnetic properties of chitosan. Glutaraldehyde was used as crosslinking agent of chitosan. The obtained magnetic chitosan was characterized by using FTIR, TGA, DSC, XRD, and SEM. Adsorption experiments were conducted with various contact time, pH and initial concentration of mercury. The results showed glutaraldehyde and FeO decreased crystallinity of chitosan. Low crystallinity of polymer is favorable for adsorption due to the high accessibility of adsorbate to reach active sites of adsorbent. FTIR and SEM confirmed the formation of magnetic chitosan. Based on correlation coefficient (R) values, the adsorption mercury by magnetic chitosan fitted with Langmuir and Freundlich isotherm models.

摘要

已开展了用于从污水中去除汞的磁性壳聚糖的制备工作。从当地铁砂中分离出磁性颗粒（FeO）以赋予壳聚糖磁性。戊二醛用作壳聚糖的交联剂。通过傅里叶变换红外光谱（FTIR）、热重分析（TGA）、差示扫描量热法（DSC）、X射线衍射（XRD）和扫描电子显微镜（SEM）对所得磁性壳聚糖进行了表征。进行了不同接触时间、pH值和汞初始浓度的吸附实验。结果表明，戊二醛和FeO降低了壳聚糖的结晶度。聚合物的低结晶度有利于吸附，因为吸附质更容易到达吸附剂的活性位点。FTIR和SEM证实了磁性壳聚糖的形成。基于相关系数（R）值，磁性壳聚糖对汞的吸附符合朗缪尔等温线模型和弗伦德利希等温线模型。
