一种多氨基改性棉纤维吸附性能研究
Adsorption Property Study on a Multi-amino-modified Cotton Fiber
摘要
Abstract
Adsorption effect and adsorption mechanism of a multi-amino-modified cotton fiber absorbing material were studied.The multi-amino-hyperbranched polymer was grafted on cotton fiber.The multi-amino-modified cotton fiber absorbing material was prepared.Adsorption property,adsorption mechanism,the optimal adsorption condition and the largest adsorption ability of cupric ion were explored.The results show that the adsorption property and adsorption capacity of multi-amino-modified cotton fiber is the best at a pH level of 5.0.The adsorption capacity is up to 17.325 5 mg/g,when the initial concentration of cupric ion in solution is 87.26 mg/L.It is considered that compared with cotton fiber and oxidative cotton fiber,adsorption capacity of the multi-amino-modified cotton fiber for cupric ion has been greatly improved.The adsorption of multi-amino-modified cotton fiber for cupric ion is chemical reactions.关键词
