Treatment Trends and Combined Methods in Removing Pharmaceuticals and Personal Care Products from Wastewater—A Review

Membranes, Journal Year: 2023, Volume and Issue: 13(2), P. 158 - 158

Published: Jan. 27, 2023

When discharged into wastewater, pharmaceuticals and personal care products (PPCPs) become microorganic contaminants are among the largest groups of emerging pollutants. Human, animal, aquatic organisms' exposures to PPCPs have linked them an array carcinogenic, mutagenic, reproductive toxicity risks. For this reason, various methods being implemented remove from water bodies. This report critically reviews these suggests improvements removal strategies. Biological, physical, chemical such as biological degradation, adsorption, membrane filtration, advanced electrical oxidation common used. However, processes were not integrated most studies take advantage different mechanisms specific each process synergistic in that differ their physical characteristics (charge, molecular weight, hydrophobicity, hydrogen bonding, structure). In review articles published date, very little information is available on use for removing PPCPs. attempts fill gap with our knowledge.

The stress of pharmaceutical and personal care products (PPCPs) discharging to water bodies the environment due increased industrialization has reduced availability clean water. This poses a potential health hazard animals human life because contamination is great issue climate, plants, humans, aquatic habitats. Pharmaceutical compounds are quantified in concentrations ranging from ng/Lto μg/L environments worldwide. According (Alsubih et al., 2022), carbamazepine, sulfamethoxazole, Lutvastatin, ciprofloxacin, lorazepam were 616–906 ng/L, 16,532–21635 694–2068 734–1178 2742–3775 ng/L respectively. Protecting preserving our must be well-driven by all sectors sustain development. Various methods have been utilized eliminate emerging pollutants, such as adsorption biological advanced oxidation processes. These their benefits drawbacks removal pharmaceuticals. Successful wastewater treatment can save bodies; integrating green initiatives into main purposes actor firms, combined with continually periodic awareness current implications environmental/water pollution, will play major role conservation. article reviews key publications on adsorption, biological, processes used remove environment. It also sheds light capability methods, efficacy concentration removal. A research gap identified for researchers explore order problem associated wastes. Therefore, future study should focus combining an excellent way products, even at low concentrations. Biological ideal circumstances microbial that enable simultaneous effects diverse efficiency.

Experimental and theoretical confirmation of CeFeCu trimetal oxide/Bi2O3 S-scheme heterojunction for boosted photocatalytic degradation of sulfamethoxazole and toxicity evaluation

Journal of Cleaner Production, Journal Year: 2023, Volume and Issue: 429, P. 139519 - 139519

Published: Nov. 3, 2023

Photocatalytic degradation of pharmaceutical pollutants in water or wastewater is becoming a hot topic for environmental clean-up. Herein, novel CeFeCu trimetal oxide (CFC TMO)/Bi2O3 (CFCB) photocatalysts were prepared through precursor mixing, ultrasonication, and calcination methods used photocatalytic sulfamethoxazole (SMZ). The pseudo-first order kinetic rate CFCB-2 catalyst on SMZ reached 0.0577 min−1 which 4.93 10.02 times higher than α-Bi2O3 CFC TMO under visible light illumination. This was proved by the strong interaction between pristine materials as confirmed XPS density functional theory (DFT) calculations. DFT calculations indicated that having more orbital distribution could make it easier to capture electrons produce radicals electron transfer. Meanwhile by-products showed no sign cytotoxicity towards human embryonic kidney cell line (HEK 293) intestinal epithelial (CACO-2). findings scavenger experiments ESR measurements •OH •O2− played superior role decomposition SMZ. Furthermore, S-scheme charge carrier transfer pathway are proposed analysed. study paves ways into promising strategy construction based heterojunction decontamination can be extended other applications such Fenton-like reactions persulfate activation.

Mediated Peroxymonosulfate Activation at the Single Atom Fe‐N₃O₁ Sites: Synergistic Degradation of Antibiotics by Two Non‐Radical Pathways

Published: March 19, 2024

Abstract The activation of persulfates to degrade refractory organic pollutants is a hot issue in advanced oxidation right now. Here, it reported that single‐atom Fe‐incorporated carbon nitride (Fe‐CN‐650) can effectively activate peroxymonosulfate (PMS) for sulfamethoxazole (SMX) removal. Through some characterization techniques and DFT calculation, proved Fe single atoms Fe‐CN‐650 exist mainly the form Fe‐N 3 O 1 coordination, exhibited better affinity PMS than traditional 4 structure. degradation rate constant SMX Fe‐CN‐650/PMS system reached 0.472 min −1 , 90.80% still be degraded within 10 after five consecutive recovery cycles. radical quenching experiment electrochemical analysis confirm are by two non‐radical pathways through 2 Fe(IV)═O induced at sites. In addition, intermediate products show toxicity attenuation or non‐toxicity. This study offers valuable insights into design carbon‐based catalysts provides potential remediation technology optimum disintegrate pollutants.
