Diclofenac (DCF), a contaminant of emerging concern, is non-steroidal anti-inflammatory drug widely detected in water bodies, which demonstrated harmful acute and chronic toxicity toward algae, zooplankton aquatic invertebrates, therefore its removal from impacted necessary. DCF recalcitrant traditional treatment technologies, thus, innovative approaches are required. Among them, electrochemical oxidation (EO) has shown promising results. In this research, an multidisciplinary approach proposed to assess the diclofenac wastewater by integrating investigations on efficiency by-product identification with disinfection capacity assessment effect environmental geno-toxicity by-products generated through oxidation. The successfully degraded achieving >98 % efficiency, operating NaCl 0.02 M at 50 A m-2. By-product analyses showed formation five parental compounds decarboxylic CN cleavage reactions. EO technique was evaluated carrying out microbiological tests pathogens generally found environments, including two rod-shaped Gram-negative bacteria (Pseudomonas aeruginosa Escherichia coli), one Gram-positive bacterium (Bacillus atrophaeus), coccus (Enterococcus hirae). Eco-toxicity freshwater organisms (algae, rotifers crustaceans) belonging trophic levels tests. Genotoxicity were carried Comet assay, relative expression catalase, manganese copper superoxide dismutase genes crustaceans. Results highlight effectiveness for degradation inactivation pathogens; however, downstream mixture results being ecosystem.

In this article, the effectiveness of adsorption techniques in removing arsenic(As) and lead(Pb) ions from typical heavy metals contaminated surface (Tac) Aponmu River at different pH values (7.2, 6.4, 3.2 11.5) was determined using powdered eggshell. The initial dosage selected water characteristics (pH, dissolved Oxygen, chloride, suspended solids, turbidity, As, oxygen (DO), Pb, chemical demand (COD)) raw determined. findings established that average dosages pollutants were 6.48, 88.73 mgl-1, 255.67 97.44 290.44 NTU, 0.79 0.55 3.71 mgl-1 188.36 mg-1, for pH, DO, COD, respectively. case adsorption, Pe able to remove 99.98 % 99.99 As Pb dosage, Adsorption kinetics range 0.12878 0.37051, 0.0782 0.31757 It concluded mechanisms these toxic (As Pb) mainly ion exchange precipitation.

A ubiquitous waste as a superior adsorbent for methylene blue removal: Cow-hair biochar

Deleted Journal, Год журнала: 2025, Номер 3(1), С. 2109 - 2109

Опубликована: Фев. 14, 2025

The efficient and sustainable removal of organic dyes from wastewater remains a critical environmental challenge. In this study, cow hair, an abundant underutilized agricultural waste, is transformed into biochar through simple pyrolysis process to develop effective eco-friendly adsorbent for methylene blue (MB) dye removal. physicochemical properties the cow-hair biochar, including its surface area, porosity, functional groups, were systematically analyzed understand adsorption performance. Batch experiments conducted under varying conditions pH, initial concentration, contact time, pH evaluate efficiency hair biochar. results revealed that exhibits superior capacity MB, driven by combination electrostatic interactions, π-π stacking, oxygen group interactions. Using R2 as criteria, best-fitting model was Temkin isotherm, indicating monolayer with maximum surpassing many conventional adsorbents, achieving high levels MB 730 mg/g. This study highlights potential converting waste high-performance adsorbent, offering cost-effective solution dye-contaminated treatment. findings pave way innovative valorization strategies contribute advancement green technologies.
