Photodegradation of Polyphenols and Aromatic Amines in Olive Mill Effluents with Ni Doped C/TiO₂

Table 4

Effect of increasing temperature values on the removals of OMW during photocatalytic degradation, at 500 mg L⁻¹ C/TiO₂/Ni nanocomposites, under 300 W UV and 30 W sunlight irradiations, after 60 min, at pH = 7.0. ( = 3, mean values).
