Decolorization of Amaranth by advanced oxidation processes
This investigation examines the decolorization of Amaranth in water by advanced oxidation processes (AOPs) - UV/TiO2, O-3, UV/O-3 and UV/TiO2/O-3. The rates of decolorization of Amaranth in UV/TiO2 followed the order pH 4 > pH 7 > pH 10; however, those for Amaranth in O-3-based systems followed the order pH 10 > pH 7 > pH 4.
