Waterborne heavy metals pose significant threats to both the environment and public health, causing neurological damage, developmental disorders, organ cancer. It is essential address contamination of various water bodies by these hazardous substances due their persistent nature lack biodegradability. This review thoroughly explores traditional modern strategies utilized remedy sources contaminated with evaluates effectiveness potential scalability each method. A literature survey reveals several effective for removing from water: adsorption, flotation, ion exchange, chemical precipitation, membrane-based filtration, coagulation, flocculation, phytoremediation, electrochemical methods. In our examination, we discussed agents/adsorbents used, efficiency removal technique, operating conditions, intrinsic advantages disadvantages approach. Summarizing key findings, noted a focus on adsorption techniques; however, challenges include selectively diverse ions, prolonged retention times, cycling stability. While membrane methods are practical, issues like large-volume sludge formation exist. Although electrical-based appear promising, solutions needed industrial-scale separation as well. Prioritizing real wastewater samples in studies crucial. Future research should emphasize eco-friendly, cost-effective

Silica aerogels modified with vinyl, epoxide, methacrylate moieties for the removal of ciprofloxacin by adsorption from water

Separation and Purification Technology, Journal Year: 2024, Volume and Issue: 354, P. 129112 - 129112

Published: Aug. 6, 2024

Water pollution caused by antibiotic effluents, particularly ciprofloxacin is a growing environmental concern. To address this problem, silica aerogels containing vinyl, epoxide, or methacrylate organic functionalities were synthesized through facile sol–gel synthesis under ambient conditions and employed as adsorbents in study. The physicochemical structural features of the materials characterized using conventional complementary techniques. Structural characterization confirmed successful chemical functionalization surface for all samples. Similar to pristine aerogel, vinyl-functionalized aerogel displayed typical mesoporous network, whereas epoxide dominantly macroporous structures. Batchwise sorption experiments performed different operating conditions. results equilibrium kinetic adsorption studies showed excellent alignment with Langmuir isotherm pseudo-second-order models, respectively. Under optimum (C0 = 100 mg/L, mads/Vsoln 0.5, pH=6, t 90 min), capacities onto methacrylate-modified 62.7, 45.8 47.8 mg/g, Despite differences at micro- meso- macrostructure level, obtaining similar adsorptive performances confirms that mechanism not only relied on pore filling but also controlled molecular interactions. exhibited repetable performance least six cycles.
