The preparation of Zr-TiO2@g-C3N4 nanocomposites to remove ciprofloxacin from water

•ZTCN was created via ultrasonic power to eliminate ciprofloxacin from aquatic phase.•Description results of the ZTCN exposed that Zr-TiO2 was effectively loaded on g-C3N4.•ZTCN nanosorbent formed had a mesoporous surface with a surface area of 71 m2/g.•The solution parameters correlated to ciprofloxacin adsorption were assessed.•Removal capability of ciprofloxacin on the ZTCN nanosorbent was 157.3 mg/g. The goal of the current study was to develop the novel nanosorbent Zr-TiO2@g-C3N4 (ZTCN) for the ciprofloxacin antibiotic elimination. Zr-TiO2@g-C3N4 (ZTCN) has been characterized using energy-dispersive system (EDX), X-Ray diffraction analysis (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and UV–visible spectrum analysis. The ability of this nanosorbent to remove the antibiotic ciprofloxacin from contaminated water was thoroughly investigated. The adsorption behavior of ciprofloxacin (CF) was studied utilizing parameters that affect absorption, such as ciprofloxacin concentration, time, temperature, pH, and dose of nanosorbent. Also, the kinetics and isotherm of the adsorbent were investigated. The results showed that the adsorption process had second-order kinetics and conformed to the Langmuir isotherm. It was found that ZTCN has a maximum adsorption capacity of 157.3 mg/g for ciprofloxacin antibiotic. According to the study's results, ciprofloxacin can be efficiently removed from contaminated water by the newly developed ZTCN nanosorbent. As a result, it can be concluded that the new nanosorbent ZTCN can be extremely relevant for application in the treatment of industrial wastewater. [Display omitted]
