Nano Colloidal Blend of Silver & Hydroxyapatite for Enhanced Photocatalytic Degradation of Toxic Methylene Blue (MB)

Updated: Jun 27

Photocatalysis has emerged as a crucial technology in addressing environmental challenges, particularly in the realm of wastewater treatment. One of the major contaminants in water is organic dyes such as methylene blue (MB), used in textile industries [1]. These organic dyes are highly water soluble and pose a threat to humans and the environment due to their toxicities [2]. In particular, traces of MB in aquatic environments attenuate the penetration of light and oxygen, limiting the photosynthesis process in aquatic plants and, in turn, misbalancing the aquatic ecosystem [3–5]. Moreover, exposure to or ingestion of MB may cause nausea, skin coloration, vomiting, diarrhea, cyanosis, and many other health conditions in humans [6–8].
