Background The heavy metal contamination of water leads to major environmental and health problems throughout the Mantaro River basin area. study assesses adsorption capacity surface-modified chak’o nano-clay for extracting lead (Pb2+) arsenic (As5+). Methods Surface modifications unmodified were achieved using through Aminopropyltriethoxysilane (APTES), iron oxide (Fe3O4), combined APTES + Fe3O4 particles. Adsorption performance was assessed batch experiments over 8 hours. BET XPS analyses conducted determine surface area, pore volume, functional group availability. kinetics modeled a pseudo-second-order model, equilibrium data analyzed Langmuir isotherm. Results dual modification produced maximum removal capacities which led 95–100% Pb2+ As5+ analysis demonstrated that area (300 m2/g 375 m2/g) volume (0.420 cm3/g 0.600 cm3/g) as well availability increased substantially thus resulting in improved adsorption. model fit kinetic while isotherm behavior describe monolayer treatment combination with generated an adsorbent better magnetic properties electrical conductivity improving its recovery potential structural stability. dual-modified showed high stability during three cycles desorption tests because it maintained more than 90% original process. Conclusion research shows specialized treatments deliver advanced absorption abilities positions leading choice sustainable system remediation.

Nanosized ceria (CeO2) and a graphitic carbon nitride-loaded (CeO2/GCN) nanocomposite were synthesized using straightforward efficient method characterized by XRD, FTIR, SEM, TEM, TGA, BET analyses. These techniques confirmed that CeO2 was effectively supported on the surface of GCN, with particle sizes CeO2/GCN composite in range 10–15 nm pore size 3.33 nm. The photocatalytic activity NPs degradation methyl red dye under sunlight radiation studied UV–visible spectroscopy. A noticeable shift compared to pure suggests reduction its band gap energy, calculated at 3.90 eV for 2.97 nanocomposite. This enhances process, achieving removal efficiency 99.92% within short irradiation time 40 min nanocomposite, 69.47% NPs. findings indicate nitride significantly properties
