A comprehensive review on sustainable clay-based geopolymers for wastewater treatment: circular economy and future outlook

Environmental Monitoring and Assessment, Год журнала: 2023, Номер 195(6)

Опубликована: Май 19, 2023

Abstract In the present era of significant industrial development, presence and dispersal countless water contaminants in bodies worldwide have rendered them unsuitable for various forms life. Recently, awareness environmental sustainability wastewater treatment has increased rapidly quest meeting global demand. Despite numerous conventional adsorbents on deck, exploring low-cost efficient is interesting. Clays clays-based geopolymers are intensively used as natural, alternative, promising to meet goals combating climate change providing low carbon, heat, power. this narrative work, review highlights persistence some inorganic/organic pollutants aquatic bodies. Moreover, it comprehensively summarizes advancement strategies associated with synthesizing clays their based geopolymers, characterization techniques, applications treatment. Furthermore, critical challenges, opportunities, future prospective regarding circular economy additionally outlined. This expounded ongoing research studies leveraging these eco-friendly materials address decontamination. The adsorption mechanisms successfully presented. Therefore, believed deepen insights into using a groundbreaking aspect accord waste-to-wealth concept toward broader sustainable development goals.

Pharmaceutically active micropollutants: origin, hazards and removal

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Опубликована: Фев. 14, 2024

Pharmaceuticals, recognized for their life-saving potential, have emerged as a concerning class of micropollutants in the environment. Even at minute concentrations, chronic exposure poses significant threat to ecosystems. Various pharmaceutically active (PhAMP), including antibiotics, analgesics, and hormones, been detected underground waters, surface seawater, sewage treatment plants, soils, activated sludges due absence standardized regulations on pharmaceutical discharge. Prolonged exposureof hospital waste facilities is linked presence antibiotic-resistant bacteria. Conventional water methods prove ineffective, prompting use alternative techniques like photolysis, reverse osmosis, UV-degradation, bio-degradation, nano-filtration. However, commercial implementation faces challenges such incomplete removal, toxic sludge generation, high costs, need skilled personnel. Research gaps include comprehensively identify understand various types micropollutants, investigate long-term ecological impact, develop more sensitive monitoring techniques, explore integrated approaches. Additionally, there gap understanding socio-economic implications pollution efficacy public awareness campaigns. Future research should delve into strategies phagotherapy, vaccines, natural substance substitutes address escalating pollution.

Extraction of ofloxacin from water using hydrophobic eutectic solvents

Journal of environmental chemical engineering, Год журнала: 2024, Номер 12(3), С. 113075 - 113075

Опубликована: Май 15, 2024

Wastewater treatment plants do not cope well with emerging micropollutants, such as pharmaceuticals, because they are effective to remove them. Therefore, this work aims develop a process for the extraction of ofloxacin (OFX) based on liquid-liquid using hydrophobic eutectic solvents (HES), coupled Conductor-like Screening Model Real Solvent (COSMO-RS) solvent screening. First, COSMO-RS was used predict partition coefficient OFX four HES families: L-menthol: fatty acid, alcohol, acid: acid and alcohols, at three different molar ratios (2:1, 1:1, 1:2). These results showed that formed by acids, especially those longer alkyl chain higher ratio, were most suitable extraction. Then, promising extract evaluated experimentally. The decanoic dodecanoic (C10 C12 acid) in ratio 2:1 being system best selected optimize conditions OFX, namely pH, HES: water (v/v), concentration, response surface methodology (RSM). obtained pH 5.2, HES-water (v/v) 1.3, 2.5 mg/ml an efficiency (98.8 ± 0.9)% could be achieved. show one-step is possible, but significantly influenced both parameters properties HES.

Assessment of Metformin Stability and Its Removal from Water by Pumice-Based Zeolite

Jurnal Penelitian Pendidikan IPA, Год журнала: 2023, Номер 9(7), С. 4909 - 4916

Опубликована: Июль 25, 2023

Metformin (MET) is an emerging contaminant often found in aquatic environments due to incompletely metabolized after consumption the human body, where some of its doses are excreted unchanged form through urine or faeces. The research aims study MET stability water and evaluate potential pumice-based zeolite for treating contaminants. Zeolites were prepared from pumice via hydrothermal treatment characterized using Fourier Transform Infrared (FTIR) X-Ray Diffraction (XRD). A simple spectrophotometric method was proposed determining aqueous solution with several different conditions. result showed that metformin unstable under strong acid conditions (pH 2), marked by loss maximum absorption peak 220-250 nm range. stable this obtained at pH solutions ranging 6 10 temperatures between 14 oC 40 oC. Furthermore, can be maintained up 3 days exposure time. Based on adsorption result, uptake capacity (196 µg/g) higher than (87 reduce concentration. In addition, synthesized needs further modification increase performance.
