The major problem facing humanity in the world right now is the sustainable provision of water and electricity. Therefore, it is essential to advance methods for the long-term elimination or removal of organic contaminants in the biosphere. Ciprofloxacin (CIP) is one of the most harmful pollutants affecting human health through improper industrial usage. In this study, a zinc tungsten oxide (ZnWO) nanomaterial was prepared with a simple hydrothermal synthesis. The ZnWO/Carbon black nanocomposites were fabricated for the determination of CIP. The nanocomposites were characterized by field emission scanning electron microscopy, energy dispersion X-ray spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and electrochemical impedance spectroscopy. Electrochemical studies were done using cyclic voltammetry and differential pulse voltammetry methods. Based on the electrode preparation, the electrochemical detection of CIP was carried out, producing exceptional electrocatalytic performance with a limit of detection of 0.02 μM and an excellent sensitivity of (1.71 μA μM cm). In addition, the modified electrode displayed great selectivity and acceptable recoveries in an environmental water sample analysis for CIP detection of 97.6% to 99.2%. The technique demonstrated high sensitivity, selectivity, outstanding consistency, and promise for use in ciprofloxacin detection. Ciprofloxacin was discovered using this brand-new voltammetry technique in a water sample analysis.
目前，人类在世界上面临的主要问题是水和电的可持续供应。因此，推进长期消除或去除生物圈中有机污染物的方法至关重要。环丙沙星（CIP）是一种因工业使用不当而影响人类健康的最有害污染物之一。在本研究中，通过简单的水热合成制备了一种锌钨氧化物（ZnWO）纳米材料。制备了ZnWO/炭黑纳米复合材料用于测定CIP。通过场发射扫描电子显微镜、能量色散X射线光谱、X射线衍射、X射线光电子能谱和电化学阻抗谱对纳米复合材料进行了表征。使用循环伏安法和差分脉冲伏安法进行了电化学研究。基于电极制备，对CIP进行了电化学检测，产生了优异的电催化性能，检测限为0.02 μM，灵敏度为（1.71 μA μM cm）。此外，在环境水样分析中，修饰电极对CIP检测显示出良好的选择性和可接受的回收率，回收率为97.6%至99.2%。该技术显示出高灵敏度、选择性、出色的一致性，并有望用于环丙沙星检测。在水样分析中，使用这种全新的伏安法技术发现了环丙沙星。
