In this paper, the adsorbents were prepared from cellulose-grafted with calix[4]arene polymers (CGC[4]P-1 and CGC[4]P-2) and their sorption properties studied. The polymers were characterized by Fourier transform infrared spectroscopy, elemental analysis, thermal gravimetric analysis and scanning electron microscopy. They were then used to evaluate the sorption properties of some heavy metal cations (Co(2+), Ni(2+), Cu(2+), Cd(2+), Hg(2+) and Pb(2+)) and dichromate anions (Cr(2)O(7)(2-)/HCr(2)O(7)(-)). Results showed that CGC[4]P-2 was a good sorbent for heavy metal cations while CGC[4]P-1 was ineffective. In the studies of dichromate anion sorption, it was observed that CGC[4]P-2 was a more highly effective sorbent at pH 1.5 than was CGC[4]P-1.
在本文中，吸附剂由接枝有杯[4]芳烃聚合物的纤维素制备（CGC[4]P - 1和CGC[4]P - 2），并对其吸附性能进行了研究。通过傅里叶变换红外光谱、元素分析、热重分析和扫描电子显微镜对聚合物进行了表征。然后用它们来评估一些重金属阳离子（Co(2+)、Ni(2+)、Cu(2+)、Cd(2+)、Hg(2+)和Pb(2+)）以及重铬酸根阴离子（Cr(2)O(7)(2-)/HCr(2)O(7)(-)）的吸附性能。结果表明，CGC[4]P - 2是重金属阳离子的良好吸附剂，而CGC[4]P - 1无效。在重铬酸根阴离子吸附研究中，观察到在pH 1.5时，CGC[4]P - 2比CGC[4]P - 1是更高效的吸附剂。
