Soil contamination by polycyclic aromatic hydrocarbons (PAHs) has been an environmental issue worldwide, which aggravates the ecological risks faced animals, plants, and humans. In this work, composites of nanoscale zero-valent iron supported on carbonylated activated carbon (nZVI-CAC) were prepared applied to activate persulfate (PS) for degradation PAHs in contaminated soil. The nZVI-CAC catalyst was characterized scanning electron microscopy (SEM), X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), photoelectron (XPS). It found that PS/nZVI-CAC system superior phenanthrene (PHE) oxidation than other processes using different oxidants (PS/nZVI-CAC > PMS/nZVI-CAC H2O2/nZVI-CAC) it also efficient six with structures molar weights. Under optimal conditions, lowest highest efficiencies selected 60.8% 90.7%, respectively. Active SO4−• HO• be generated surface catalysts, dominant PHE through quenching experiments. results demonstrated heterogeneous process PS effective PAH degradation, could provide a theoretical basis remediation PAH-polluted

Study’s Novelty/Excerpt This study presents comprehensive overview of the roles various bacterial genera, including Alcaligens, Achromobacter, and Bacillus, in biosorption chromium from contaminated soils, highlighting specific factors influencing efficiency. It uniquely addresses optimization environmental conditions such as pH, temperature, nutrient availability to enhance large-scale processes, bridging gaps noted previous literature regarding scalability biosorption. Additionally, manuscript underscores necessity for further research biotechnology molecular engineering fully harness potential remediation, presenting a forward-looking perspective on advancing this bioremediation strategy. Full Abstract Chromium possesses detrimental effects health both plants animals. Biosorption is process where biological materials (bacteria, fungi, algae, or agricultural waste) are used remove pollutants sites. Conventional methods remediating heavy metal-contaminated excavation chemical treatment, expensive disruptive, making them less desirable. Factors efficiency promising approaches involving bacteria metals Chromium, lead, nickel, cadmium, arsenic, etc., soil. Some genera involved include Acinetobacter, Alteromonas, Arthrobacter, Burkholderia, Enterobacter, Flavobacterium, Pseudomonas. These can adsorb biotransform into toxic forms. concentration, surface compositions, metal ion characteristics, soil composition. Challenges associated with using biosorption, outlined literature, slowness fact that it may not be suitable application, even though many other authors have proven its applicability large scale. Also, key quality needed biosorbent must tolerating metals. Another area focus current optimizing conditions, availability, achieve more efficient at larger highlighted strategy Conclusively, has great use Chromium- realize potential, especially engineering.

In recent years, pollution stemming from pharmaceuticals has garnered widespread global concern, which exacerbates the ecological risk to both surface and groundwater. current study, Fe O co-embedded biochar (Fe-O-BC) was synthesized through a one-step pyrolysis procedure with corncob serving as feedstock. The fabricated Fe-O-BC catalysts were characterized by various techniques employed for activation of peroxymonosulfate (PMS) degrade tetracycline (TC). TC rapidly degraded within 40 min, degradation rate 0.1225 min−1, much higher than those O-BC/PMS (0.0228 min−1) Fe-BC/PMS (0.0271 under same conditions. effects PMS dosage, dose, initial pH value coexisting anions investigated.
