Sunlight-activated carbon nanotubes for anionic dye removal: characterization, efficiency, and biological assessment against some aquaculture and human pathogenic bacteria (opens in new tab)

Ammonia-functionalized multi-walled carbon nanotubes (MWCNTs/NH₃) were synthesized and evaluated for the sunlight-enhanced removal of Acid Red 73 (AR73) dye, as well as to assess its potential application against aquaculture and human pathogenic bacteria. Characterization of FTIR, SEM, and EDX confirmed a porous structure (70–110 nm diameters). FTIR confirmed functional groups (O-H, N-H, C ≡ C, C = C) critical for dye adsorption. SEM revealed a porous, entangled MWCNT structure with high surf...
