In the present work, a tubular nano-copper sulfide was successfully synthesized by hydrothermal method. The physical and chemical properties of the prepared materials were characterized by XRD, SEM, TEM, and BET. The synthesized copper sulfide was used as an adsorbent for removing 17α-ethynyl estradiol (EE2) and exhibited excellent adsorption properties. At 25 °C, 15 mg of adsorbent was applied for 50 mL of 5 mg/L EE2 solution, adsorption equilibrium was reached after 180 min, and the adsorption rate reached nearly 90%. In addition, the kinetics, isothermal adsorption, and thermodynamics of the adsorption process were discussed on the basis of theoretical calculations and experimental results. The theoretical maximum adsorption capacity of copper sulfide was calculated to be 147.06 mg/g. The results of this study indicated that copper sulfide was a stable and efficient adsorbent with promising practical applications.
在本工作中，通过水热法成功合成了管状纳米硫化铜。采用X射线衍射仪（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和比表面积分析仪（BET）对所制备材料的物理和化学性质进行了表征。合成的硫化铜用作去除17α-乙炔基雌二醇（EE2）的吸附剂，并表现出优异的吸附性能。在25℃下，将15mg吸附剂用于50mL 5mg/L的EE2溶液，180min后达到吸附平衡，吸附率近90%。此外，基于理论计算和实验结果对吸附过程的动力学、等温吸附和热力学进行了讨论。计算得出硫化铜的理论最大吸附容量为147.06mg/g。本研究结果表明，硫化铜是一种稳定且高效的吸附剂，具有良好的实际应用前景。
