Surface-imprinted polymer microsphere based on self-stabilized precipitation polymerization for selective removal of norfloxacin

“…For example, activated sludge may have negative impacts on microorganisms and generate highly hazardous secondary pollutants. However, the membrane filtration technique is proven to be highly effective, but it also possesses some challenges including high cost, energy-intensive nature, and sensitivity to membrane fouling. , The ultrasonic cavitation technique has been demonstrated as an advanced, economical, and small-scale approach for wastewater treatment but demands substantial energy input during its operation …”

The discharge of antibiotics into the aquatic environment can become toxic and hazardous to both human health and the environment. Therefore, it is enormously essential to remove multiple antibiotics from the wastewater. In this work, carbon nano-onions (CNOs) were synthesized and used as effective adsorbents for the removal of 97% norfloxacin (NOR) and 99% tetracycline hydrochloride (TCH) antibiotics from wastewater. CNOs showed good adsorption efficiency, and the equilibrium period was also short. The adsorption studies were investigated with adsorbent dosages, adsorbate concentration, and pH. The maximum adsorption capacity (q max) was found to be 416.66 and 344.82 mg g–1 for TCH and NOR, respectively. CNOs have also shown admirable removal efficiency toward NOR and TCH from natural water samples such as dam water (97% TCH and 94% NOR), tap water (96% NOR and 93% TCH), and lake water (95% NOR and 93% TCH).

“…Molecularly imprinted polymers (MIPs) are a type of synthetic polymer that can be specifically fabricated to resemble the binding properties of antibodies or enzymes. 18 They are created by "imprinting" a target molecule into a polymer matrix, and then removing the target molecule. This leaves behind a cavity with a specific recognition ability that has the same shape, size and functionality as the template molecule and so, template molecule can selectively bind to the cavity.…”

Streptomycin is a type of aminoglycoside used in treatment of several infections and with serious side effects in humans and animals, such as ototoxicity and nephrotoxicity. In the present study, we focused on the preparation of streptomycin‐imprinted cotton fiber for rapid, sensitive and selective quantification of streptomycin in honey samples. The imprinted cotton fibers were characterized by attenuated total reflectance‐Fourier transform spectroscopy, scanning electron microscopy, and x‐ray photoelectron spectroscopy. In addition, the imprinted cotton fibers showed high adsorption capacity (95.4 mg/g) with an imprinting factor of 3.69 and had satisfactory regeneration ability of up to 10 regenerations without significant change in adsorption capacity. The imprinted cotton fibers showed good linearity with a correlation coefficient of 0.9989 and limit of detection was determined to be 0.29 ng/mL for streptomycin in honey samples. The proposed method showed acceptable recovery ranges (98.0%–100.3%) with lower inter‐day and intra‐day precisions. Moreover, the performance of the proposed method was compared to the ELISA method. The results showed that the present method is as sensitive and selective as ELISA. It is concluded that the imprinted cotton fibers could be a potential alternative to antibiotic quantification based on traditional immunoassays or chromatographic techniques.
