Abstract

With the increase in petrochemical energy consumption and the limited reserves, the abundant and cheap sustainable biomass resources have been more space for development. Abandoned feather fiber (FF) is the main by-product of the poultry industry. It not only depletes resources unnecessarily, but also causes environmental damage. Uranium adsorption material made from waste feather fiber is a high value-added conversion of waste resources. In this study, phosphate ester group was used to modify the waste feather fiber to prepare an adsorption material (FF-EDGE-PT) with high affinity for uranium. FF-EDGE-PT had an absorption capacity (AC) of 268.45 ± 14.84 mg/g for uranium in a solution containing a uranium concentration of 8 ppm. The Langmuir isotherm model fitting reveals that FF-EDGE-PT has a maximum saturated AC of 877.19 mg/g. More importantly, FF-EDGE-PT also exhibits excellent recycling performance and selective adsorption, indicating that FF-EDGE-PT is a potential uranium adsorption material.

废弃羽毛纤维的价值评估：一种铀资源回收材料

随着石化能源消耗的增加和储量的有限，丰富而廉价的可持续生物质资源有了更大的发展空间。废弃羽毛纤维（FF）是家禽业的主要副产品。它不仅会无谓地消耗资源，还会对环境造成破坏。利用废弃羽毛纤维制成的铀吸附材料是一种高附加值的废弃资源转化物。本研究利用磷酸酯基团对废羽毛纤维进行改性，制备出一种对铀具有高亲和力的吸附材料（FF-EDGE-PT）。在铀浓度为 8 ppm 的溶液中，FF-EDGE-PT 对铀的吸收能力（AC）为 268.45 ± 14.84 mg/g。朗缪尔等温线模型拟合显示，FF-EDGE-PT 的最大饱和 AC 值为 877.19 毫克/克。更重要的是，FF-EDGE-PT 还表现出优异的回收性能和选择性吸附能力，表明 FF-EDGE-PT 是一种潜在的铀吸附材料。
