Effect of Calcination Temperature on the Adsorption Performance of Mg/Al Layered Double Hydroxide Nanoparticles in the Removal of Meropenem Antibiotics

“…Drinking water, ground water, surface water, and sewage discharge have all had traces of antibiotics and other pharmaceuticals identified within them (2,40). Livestock and human excretion, hospital wastewater, pharmaceutical effluent, and other such sources lead to the pollution of aquatic environments by pharmaceuticals (1,37). Bacteria can form resistance to antibiotics following changes to microbial communities that stem from antibiotics being present in the environment (20, 57).…”

“…Diverse water sources have undergone multiple techniques to expunge the presence of antibiotics in the last decade or so. These include advanced oxidation processes (48), ozonation (9), electrocoagulation process (37,38), extraction (8), Photo-Degradation by UV and UV/TiO2 Processes (43), nanofiltration membranes (25), chlorination (2), and Adsorption are among the mentioned techniques (23). The existence of multiple ratecontrollable parameters, high removal efficacy, suitability for application over a large concentration range of sorbate, and low instrumentation cost are among the significant benefits of the adsorption process, making it one of the most efficient methods (11).…”

“…6. Impact of pH on removal efficacy of MER (temperature = 25°C, adsorbents dose = 0.5 g/50 mL, contact time = 4 hour, agitation speed = 150 rpm, Co = 100 mg L -1 )Impact of initial MER concentrationWithin the adsorption process, a substantial supportive factor is the initial concentration of the pollutant, which, in turn, can help surpass the mass transmission resistance of dissolved materials among the aquatic and solid stages(37). As illustrated in Figure7, a contact time of 240 min, adsorbents dosage of 0.5 g/50 mL, and pH 6 was used to analyze the removal efficacy and how it is impacted by the initial concentration of MER which was between 10 and 350 mg L -1 .…”

Enhanced ciprofloxacin removal from aqueous solution using a chemically modified biochar derived from bamboo sawdust: Adsorption process optimization with response surface methodology

“…Conventional wastewater treatment methods are unable to sufficiently remove CIP from water, owing to CIP's biodegradation resistance (Ghadiri et al, 2020;Liang et al, 2018). In response to this problem, removal mechanisms such as ozonation (Bilal et al, 2021), catalytic oxidation (Nemati et al, 2019), photocatalytic degradation of CIP with hematite (Fe 2 O 3 ) nanoparticles (Rajiv et al, 2021), electro-Fenton (Mi et al, 2018), electrocoagulation (Mohammed et al, 2021), magnetic nanomaterials (Chang et al, 2021) reverse osmosis (Río-gamero et al, 2018), solar photo-oxidation (Tawfik et al, 2022) and adsorption (Liang et al, 2018;Río-gamero et al, 2018;Ezekoye et al, 2020) have been explored for the removal of CIP from water. Among the advanced oxidation processes mentioned above, solar photo-oxidation is recently considered a promising way of degrading recalcitrant pollutants in industrial wastewater.…”

Metagenomic Analysis of the Long-Term Synergistic Effects of Antibiotics on the Anaerobic Digestion of Cattle Manure

“…These antimicrobials inhibit the AD process, induce changes in microbial communities, promote the spread of drug resistance (DR), and influence the efficiency of biogas and CH 4 production [11]. Research has demonstrated that fluoroquinolones are highly persistent in the environment, and that the efficiency of fluoroquinolone removal during AD is close to zero [12]. In the livestock industry, MET is used mainly to treat infections caused by anaerobic bacteria [13].…”
