Abstract

The present article describes novel massive materials (in the solid phase) based on TEGylated phenothiazine and chitosan that possess great capability to recover mercury ions from constituent aqueous solutions. These were produced by chitosan hydrogelation accompanied by formyl subsidiary item of TEGylated phenothiazine, attended by lyophilization. The delineation and structure description of the obtained material or supramolecular assembly were realized by FTIR (Fourier transform infrared) spectroscopy, X-ray diffraction, and POM (Polarized Light Optical Microscopy). The morphology of their texture was kept under observation by SEM (Scanning Electron Microscopy). The obtained SEM images were evaluated by fractal analysis. The fractal parameters of interest were calculated, including the fractal dimension and lacunarity.

摘要

本文描述了基于聚乙二醇化吩噻嗪和壳聚糖的新型块状材料（固相），其具有从组成水溶液中回收汞离子的强大能力。这些材料是通过壳聚糖水凝胶化并伴有聚乙二醇化吩噻嗪的甲酰基附属物，随后进行冻干制备而成。通过傅里叶变换红外光谱（FTIR）、X射线衍射和偏光光学显微镜（POM）对所得材料或超分子组装体进行了描绘和结构表征。通过扫描电子显微镜（SEM）观察其纹理形态。通过分形分析对获得的SEM图像进行评估。计算了感兴趣的分形参数，包括分形维数和空隙率。
