Pharmaceuticals and Personal Care Products as Emerging Environmental Contaminants: Prevalence, Toxicity, and Remedial Approaches

“…Tetracycline hydrochloride (TH) and naproxen (NPX) were studied to check the efficiency of the composite, FeCNT@C 3 N 4 , and found effective for the purpose. 39 Adsorption-based methods are definitely an effective choice for treating PPCP-polluted wastewater; however, such approaches might exist with some drawbacks like high investment, elevated operational costs, low efficiency, and potential toxicity of adsorbents, particularly the nanoadsorbents. 185 of availability, processing, economical aspects, and environmental fate in more detail.…”

“…Activated carbon has been the primary choice for this purpose for many years, but new catalytic systems have been found to be more advantageous due to their own characteristic features to overcome the shortcomings associated with this already established adsorbent. A number of diversely functionalized materials have been documented in recent literature. − Moreover, several biological, physical, and chemical methodologies also effectively remove PPCPs from the environmental samples . (Table ).…”

Engineering an iron atom-cluster nanostructure towards efficient and durable electrocatalysis

“…S8B †) of Fe SA /Fe AC -NC 900 could be categorized into four peaks at about 288.5, 286.2, 285.6, and 284.8 eV, equivalenting to O]C-O, C-O, C-N and C]C groups, respectively. 35 The N 1s spectra of Fe SA /Fe AC -NC 900 can be deconvoluted into ve peaks, which are attributed to 403.4 eV (oxidized N), 401.2 eV (graphitic N), 400.2 eV (pyrrolic N), 399.4 eV (Fe-N x ), and 398.6 eV (pyridinic N), respectively (Fig. S8C †).…”

Accelerated Fenton degradation of azo dye wastewater via a novel Z-scheme CoFeN-g-C3N4 heterojunction photocatalyst with excellent charge transfer under visible light irradiation

“…S3b †) that there are four typical peaks at 284.8, 285.9, 288.7 and 289.1 eV, which belong to C-C/CvC, C-NH2, C-N/CvN and graphitic C, respectively. 29 The graphitic C and graphitic N structures existing in CFN-CN1 can provide more electrons and promote the conductivity of the catalyst, 30 thereby enhancing the photoelectric activity of the catalyst.…”
