Abstract
This study addresses the pressing concern of dye effluent contamination in water bodies and proposes a multifaceted solution through the synthesis and application of Manganese cobalt oxide (MnCo 2 O 4 ) nanoparticles . The nanoparticles were prepared hydrothermally using acetate precursors, and their composition was carefully confirmed by XRD, FTIR, UV-DRS, FESEM, and EDX studies. The prepared MnCo 2 O 4 nanoparticles, when exposed to the best-suited conditions (20 mL of dye solution containing 2.5 mg of MnCo 2 O 4 NP kept at direct sunlight for 24 h, reaction time), exhibited remarkable efficiency in completely breaking down inorganic dyes, with removal percentages of 78.8 % for Methyl blue (MB) and 97.6 % for Congo red (CR). Notably, the synthesized MnCo 2 O 4 nanoparticles display strong antibacterial capabilities against multidrug-resistant bacteria and considerable anticancer effects on the cervical cancer cell line (HeLa), as verified by the MTT assay. This comprehensive investigation positions the MnCo 2 O 4 nanoparticle as a promising candidate for efficient wastewater treatment, a robust antibacterial agent, and a potential therapeutic agent against cervical cancer, highlighting its diverse and impactful applications.
