Abstract

Drugs are essential pollutants in the environment due to their resistant structure, and their high consumption in treating humans and animals. The entry of antibiotics as hospital waste into aquatic environments is considered one of the critical environmental means due to their high stability. The design and synthesis of Fe 2 O 3 /Ag/Zn as a new structure of Fe 2 O 3 were reported, because of its resis- tance of the structure to air and high temperature, the adsorbent of azithromycin in wastewater was studied. After characterization of Fe 2 O 3 /Ag/Zn by scanning electron microscopy, energy-dis- persive X-ray spectroscopy, mapping, transmission electron microscopy, X-ray diffraction and Fourier-transform infrared spectroscopy. Then, to remove azithromycin, the effect of factors such as pH, the concentration of azithromycin solution, adsorbent dose, time and temperature was evalu-ated using an optimization process. The results showed that the optimal conditions for removing of 96% of azithromycin (10 mg/L) with 1.5 g/L of Fe 2 O 3 /Ag/Zn, pH = 5, and 30 min at room temperature, In other words, the nano absorbent has a good ability to remove azithromycin from water solution, which is very important from environmental aspects.

Fe2O3/Ag/Zn纳米复合材料去除水溶液中阿奇霉素的研究

药物由于其耐药结构，以及在治疗人类和动物时的高消耗，是环境中必不可少的污染物。抗生素作为医院废弃物进入水生环境，由于其高稳定性，被认为是关键的环境手段之一。本文设计合成了fe2o3 /Ag/Zn作为一种新型fe2o3结构，由于该结构对空气和高温的抗性，对废水中阿奇霉素的吸附剂进行了研究。通过扫描电镜、能量色散x射线能谱、作图、透射电镜、x射线衍射和傅里叶变换红外光谱对fe2o3 /Ag/Zn进行表征。然后，采用优化工艺考察了pH、阿奇霉素溶液浓度、吸附剂用量、时间、温度等因素对去除阿奇霉素的影响。结果表明，在1.5 g/L Fe 2o3 /Ag/Zn、pH = 5、30 min的室温条件下，纳米吸附剂对阿奇霉素(10 mg/L)的去除率为96%，表明纳米吸附剂对水溶液中阿奇霉素的去除率较好，具有重要的环境意义。
