Abstract

The discharge of untreated dye waste from various industrial sectors into wastewater poses significant environmental and health risks. This study presents an innovative approach by developing a cost-effective and eco-friendly hybrid mesoporous nanocomposite, silver nanoparticles@mesoporous mango peel-derived carbon (AgNPs@MMC), synthesized from agricultural waste (mango peels) and urban waste (X-ray film waste). The core objectives of this work are: (i) recycling agricultural and urban waste to produce valuable materials; (ii) achieving effective removal of methyl violet 10B (MV10B) through simultaneous adsorption and photocatalytic degradation; and (iii) evaluating the antimicrobial properties of the developed material. The findings for identifying the optimal parameters for the adsorption and photodegradation process showed that 25 mg of AgNPs@MMC can remove >98% of the MV10B dye in 30 min at pH of 7. Furthermore, the nanocomposite maintained its high efficiency for five reuse cycles without significant loss in performance. This work highlights the dual functionality of AgNPs@MMC, combining adsorption and catalytic degradation, while also showcasing its potential for practical wastewater treatment applications. The nanocomposite's structural stability in water and its superior antibacterial activity against Gram-negative bacteria, such as Escherichia coli, Pseudomonas vulgaris, and Vibrio parahaemolyticus, further confirm its environmental suitability.
