Iron oxide/biochar (FeO/biochar) was prepared by green synthesis a microwave to evaluate ultrasound-assisted adsorption capacity of Nonsteroidal Anti-inflammatory Drugs (NSAIDs) (salicylic acid, naproxen, and ketoprofen) from the water. Several techniques of characterization, including, Fourier transform infrared spectrometry, scanning electron microscopy, EDS analysis, N adsorption-desorption, X-ray diffraction, and Raman spectrometry were applied. The adsorption of NSAIDs onto FeO/biochar was performed using an ultrasonic bath. The effects of batch adsorption under various experimental parameters such as contact time (0-120 min), initial concentration (10-500 mg L) and pH (2-12) were tested. The obtained FeO/biochar specific surface area, mesopore volume/micropore volume, and pores size were equal to 786 m g, 0.409 cm g, and 1.534 cm g, respectively. The pseudo-second-order model could describe better all NSAID adsorptions onto FeO/biochar. The Langmuir model agreed well with the NSAID adsorptions and the maximum adsorption capacities reached 683 mg g, 533 mg g and 444 mg g for salicylic acid, naproxen, and ketoprofen, respectively. FeO/biochar can be used as an excellent adsorbent for the treatment of NSAIDs in water.
通过绿色合成法利用微波制备了氧化铁/生物炭（FeO/生物炭），以评估其对水中非甾体抗炎药（NSAIDs）（水杨酸、萘普生和酮洛芬）的超声辅助吸附能力。应用了几种表征技术，包括傅里叶变换红外光谱法、扫描电子显微镜、能谱分析、N吸附-脱附、X射线衍射和拉曼光谱法。使用超声浴进行NSAIDs在FeO/生物炭上的吸附。测试了在各种实验参数（如接触时间（0 - 120分钟）、初始浓度（10 - 500 mg/L）和pH值（2 - 12））下的批量吸附效果。所制备的FeO/生物炭的比表面积、中孔体积/微孔体积和孔径分别为786 m²/g、0.409 cm³/g和1.534 cm³/g。准二级模型能更好地描述所有NSAIDs在FeO/生物炭上的吸附情况。朗缪尔模型与NSAIDs的吸附情况吻合良好，水杨酸、萘普生和酮洛芬的最大吸附容量分别达到683 mg/g、533 mg/g和444 mg/g。FeO/生物炭可作为处理水中NSAIDs的优良吸附剂。
