The composite material SBC-Fe-x with sludge and Fe was developed by different calcination temperatures (600, 700, and 800 °C) for the removal of tetracycline (TC). The adsorption rates of SBC-Fe-600, SBC-Fe-700, and SBC-Fe-800 were 77.5%, 89%, and 91%, respectively. Furthermore, the Langmuir model indicated that the maximum adsorption capacity of SBC-Fe-700 (157.93 mg/g) was three times greater than that of SBC-Fe-600. The conclusions were confirmed by a series of characterizations that SBC-Fe-700 showed a larger specific surface area, well-developed pore structure, rich oxygen-containing functional groups and a high degree of graphitization. The results of pH experiments indicated the broad applicability of SBC-Fe-700 for TC adsorption. In addition, SBC-Fe-700 suggested outstanding performance in different water environments. This work produced a feasible adsorbent for the removal of TC, and a new direction for sludge resource utilization was proposed.
开发了一种由不同煅烧温度（600、700 和 800°C）制备的复合材料 SBC-Fe-x（包含污泥和 Fe），用于去除四环素（TC）。SBC-Fe-600、SBC-Fe-700 和 SBC-Fe-800 的吸附率分别为 77.5%、89%和 91%。此外，Langmuir 模型表明，SBC-Fe-700 的最大吸附容量（157.93 mg/g）是 SBC-Fe-600 的三倍。一系列特性的证实了这一结论，表明 SBC-Fe-700 具有更大的比表面积、发达的孔结构、丰富的含氧官能团和高石墨化程度。pH 值实验结果表明，SBC-Fe-700 对 TC 吸附具有广泛的适用性。此外，SBC-Fe-700 在不同水环境中表现出优异的性能。这项工作为去除 TC 提供了一种可行的吸附剂，并为污泥资源利用提出了新的方向。
