Abstract

Novel superabsorbent polymers (SAPs) were synthesized by performing aqueous solution graft copolymerization of potato starch xanthate and partially hydrolyzed acrylamide using N,N′-methylene-bis-acrylamide as a crosslinker and potassium persulfate as an oxidant at 35–45°C. Various factors that influence the water absorption of SAPs were studied in detail, and the optimum formulation ratio was determined via orthogonal experiments. Several spectroscopic techniques, including scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, and transmission electron microscopy, were used to determine the structure of the SAPs. In addition, adsorption experiments were carried out with various heavy metal ions, including divalent copper ions, zinc ions, nickel ions, cobalt ions, cadmium ions, and lead ions. Experiments showed that the prepared SAP has a high adsorption performance (>48 mg·g−1). Thus, these materials are expected to have important applications in the removal of heavy metal ions and the separation of dyes in aquatic environments.

由聚（马铃薯淀粉黄原酸盐-接枝-丙烯酰胺）衍生的新型超吸附聚合物的设计、合成、表征和吸附能力

以 N,N′-亚甲基双丙烯酰胺为交联剂，过硫酸钾为氧化剂，在 35-45°C 温度条件下，通过水溶液接枝共聚马铃薯淀粉黄原酸盐和部分水解丙烯酰胺，合成了新型超吸水性聚合物（SAP）。详细研究了影响 SAP 吸水性的各种因素，并通过正交实验确定了最佳配方比例。为了确定 SAP 的结构，使用了多种光谱技术，包括扫描电子显微镜、傅立叶变换红外光谱、热重分析和透射电子显微镜。此外，还进行了各种重金属离子的吸附实验，包括二价铜离子、锌离子、镍离子、钴离子、镉离子和铅离子。实验表明，制备的 SAP 具有很高的吸附性能（48 mg-g-1）。因此，这些材料有望在去除重金属离子和分离水生环境中的染料方面得到重要应用。
