Industrial streams are the source of increasing amounts of textile dye pollution every year. Among the various adsorbents that have been tested for the removal of dyes, synthetic macroporous polymers are a promising choice due to their developed structure, the presence of active functional groups, and the possibility of regeneration and reuse for several cycles. In this work, a 4-vinylpyridine-co-methacrylic acid based cryogel (4-VP-MAAc) was synthesized at -12 °C by the free-radical polymerization technique, it was characterized using a set of complimentary methods, and then applied for the removal of methylene blue (MB) from water solutions.

新型 4-乙烯基吡啶-共-甲基丙烯酸冷冻凝胶有效去除亚甲基蓝染料：动力学、等温线和突破性研究

工业流是每年增加的纺织染料污染的来源。在已经测试用于去除染料的各种吸附剂中，合成大孔聚合物是一种很有前途的选择，因为它们具有发达的结构、活性官能团的存在以及再生和重复使用多个循环的可能性。在这项工作中，采用自由基聚合技术在-12 ℃下合成了一种基于 4-乙烯基吡啶-共甲基丙烯酸的冷冻凝胶 (4-VP-MAAc)，并使用一组互补的方法对其进行了表征，然后应用于用于从水溶液中去除亚甲基蓝 (MB)。
