Abstract:

禽类羽毛是资源丰富、价格低廉的天然高分子材料,使用单宁酸对其进行化学改性,研究了改性前后羽毛对金属铜离子的吸附及解吸性能,探讨了羽毛上单宁酸负载量、溶液温度、铜盐溶液的pH值等因素对羽毛的金属离子吸附性能的影响。结果表明,经单宁酸化学改性的羽毛在碱性环境下能明显增加对金属铜离子的吸附,此时对应Cu2+的最大吸附量为48.90mg·g-1,而未改性羽毛在相同条件下的最大吸附量为26.67mg·g-1;在酸性环境中,改性羽毛中金属铜离子的解吸附率为13.0%,未改性羽毛的铜离子解吸附率为35.7%,表明改性羽毛的金属复合物具有较高的稳定性。可见羽毛作为一种廉价的重金属吸附材料,在整治环境污染方面具有应用前景。
