摘要
利用自制的弱酸性离子交换纤维对水中的氨和5种有机胺进行了吸附实验研究。结果表明,该纤维材料对氨和有机胺具有明显的吸附效果。吸附后纤维有明显的增重,而且发现,吸附目标物的分子尺寸越大,通常其吸附量越小。力学性能测试表明,纤维的断裂力与吸附目标物的分子结构有关系。红外光谱测试表明,纤维的化学结构在吸附后发生了明显的变化,说明氨和有机胺与纤维之间发生的是化学吸附。
Ammonia and 5 organic amines are found to be effectively adsorbed by the self - made weekly acidic ion - exchange fiber. The fiber has got a remarkable weight increase after adsorption, and it is found that the adsorption amount decreased when the molecular size become larger. Mechanical test results show that the break force of the fiber after adsorption is influenced by the chemical structure of the absorbed molecules. Infrared spectrum shows that the chemical strcture of the fiber after adsorption is quite different with the original fiber,which disclose that the ammonia and amines are chemically adsorbed by the fiber.
