Abstract

Remazol Brilliant Blue R (RBBR), an anthraquinone-based dye, has emerged as a contaminant in water sources, posing ecological threats. This study explores the photocatalytic degradation and adsorption of RBBR and its byproducts using a biocompatible HAp-ZnO nanocomposite. The nanocomposite was synthesized for its optical and antibacterial properties. The combined experimental and theoretical approach aims to elucidate the degradation mechanism. Under UV irradiation, the nanocomposite effectively eliminates RBBR (> 93%) and inhibits bacterial growth. The high efficiency is attributed to the interaction between photogenerated electrons and hydroxyl radicals during UV exposure. These findings demonstrate the potential of HAp-ZnO nanocomposites for dye remediation and highlight the value of nanocomposite materials in developing advanced photocatalysts for wastewater treatment.
