Effective wastewater treatment remains a critical challenge, especially when dealing with hazardous pollutants like antimony (Sb(III)). This study addresses this issue by using innovative nanocomposites to remove Sb(III) ions from water, while simultaneously repurposing the spent adsorbents for energy storage applications. We developed reduced graphene oxide-NiFe2O3-SiO2-polyindole (RGO-NiFe2O3-SiO2-PIn NCs) via hydrothermal synthesis method, achieving high removal efficiency of 91.84% at an initial concentration 50 mg/L pH 8. After adsorption, exhausted adsorbent was repurposed storage, effectively minimizing secondary pollution. The Sb(III)-loaded (RGO-NiFe2O3-SiO2-PIn@SbOx) exhibited excellent performance as material, specific capacitance (Cs) 701.36 F/g current density 2 A/g and retention rate 80.15% after 10,000 cycles. dual-purpose approach not only advances technologies but also contributes sustainable economical recycling practices, particularly in field storage.

Efficient wastewater treatment, particularly the removal of heavy metal ions, remains a challenging priority in environmental remediation. This study introduces novel sandwich-structured nanocomposite, RGO-CuS-PPy, composed reduced graphene oxide (RGO), copper sulfide (CuS), and polypyrrole (PPy), synthesized via straightforward hydrothermal method. The unique combination RGO, CuS, PPy offers enhanced adsorption capacity for Ni(II) ions due to RGO's high surface area CuS's active binding sites, supported by PPy's structural stability contributions. is among first explore this specific nanocomposite architecture removal, achieving an 166.67 mg/g efficiency 94.9% within 210 min 55 mg/L concentration at pH 6 adsorbent dose 3 mg/15 mL. kinetic analysis shows best fitted time-dependent experimental data with pseudo-second-order model, indicating chemisorption. Isotherm studies confirmed Langmuir model as fit, yielding monolayer mg/g. Thermodynamic process was endothermic (ΔH° = 80.23 kJ/mol) spontaneous (ΔG° ranging from -6.985 -14.399 kJ/mol). Additionally, reusability tests using 0.1 M HCl desorption demonstrated good reusability, emphasizing RGO-CuS-PPy nanocomposite's potential sustainable treatment applications.
