Enhancement of degradation of mordant orange, safranin-O and acridine orange by CuS nanoparticles in the presence of H2O2 in dark and in ambient light

Enhancement of degradation of mordant orange, safranin-O and acridine orange by CuS nanoparticles in the presence of H2O2 in dark and in ambient light

CuS nanoparticles synthesized by solid-state reaction were used to remove Mordant Orange (MO), Acridine Orange (AO), and Safranin-O (SO) from water. Average diameter, band gap and surface area of CuS nanoparticles were 50 nm, 3.2 eV and 1.52 m 2 /g respectively. CuS nanoparticles removed 22%, 45%, 5...

Zusammenfassung:CuS nanoparticles synthesized by solid-state reaction were used to remove Mordant Orange (MO), Acridine Orange (AO), and Safranin-O (SO) from water. Average diameter, band gap and surface area of CuS nanoparticles were 50 nm, 3.2 eV and 1.52 m 2 /g respectively. CuS nanoparticles removed 22%, 45%, 51% SO, AO, and MO in 180 min respectively. Addition of H 2 O 2 resulted in 100% removal of dyes in 180 min in ambient light and 75% dye removal in dark. H 2 O 2 also increased apparent reaction rate constant ( K app ). Details of dye removal mechanism by CuS nanoparticles and enhanced dye removal due to H 2 O 2 is provided.
