摘要
本研究首先从造纸污泥制备炭化物(CCP),再利用磷酸/硝酸混合液活化CCP,制备造纸污泥基活性炭(ACPMS)。将ACPMS用于抗生素恩诺沙星(ENF)的吸附去除。结果表明,ENF在ACPMS上的吸附过程符合朗格缪尔等温线模型和准二阶动力学模型,最大吸附能力为46.8 mg/g,表明ACPMS可以高效吸附ENF,是一种从环境基质中去除抗生素的有效工具。
In this study,carbonized papermaking sludge(CCP)was prepared firstly,and then activated carbon based on papermaking sludge(ACPMS)was synthesized by activating CCP with a mixture of phosphoric acid and nitric acid.The ACPMS was then utilized for the adsorption removal of the antibiotic enrofloxacin(ENF)and the findings revealed that the adsorption of ENF on ACPMS conformed to the Langmuir isotherm model and the quasi second-order kinetic model with a maximum adsorption capacity of 46.8 mg/g.The results showed that the high efficiency of ACPMS in adsorbing ENF,highlighting its potential as an effective tool for removing antimicrobial agents from en⁃vironmental matrices.
