摘要
以聚乙烯醇(PVA)、壳聚糖和明胶为原料、戊二醛为交联剂,在酸性溶液中通过共混交联反应合成了聚乙烯醇/壳聚糖/明胶水凝胶,单因素法讨论了影响水凝胶性能的因素如:反应物质量比、交联剂用量、反应温度、反应时间等聚乙烯醇/壳聚糖/明胶水凝胶,对不同浓度苯酚溶液的吸附研究。研究结果表明聚乙烯醇/壳聚糖/明胶水凝胶对苯酚有较好的吸附性能。
Starting from polyvinyl alcohol,chitosan and gelatin,polyvinyl alcohol/chitosan/gelatin hydrogel was ob- tained in acidic solution via crosslinking reaction using glutaraldehyde as crosslinking agent. The factors affecting the hydro- gel activity of absorption of phenol in different concentration solutions, such as ratio between reactants,loading of crosslink- ing agent, reaction temperatures and reaction time,were investigated by single-factor method. The result proved that polyvi- nyl alcohol/chitosan/gelatin hydrogel showed a good absorption activity of phenol.
