Description:
This research demonstrates the comparison between copper (II) sulphate (CuSO 4 ) and zinc oxide (ZnO) as thermalcatalysts in thermolysis process for the treatment of diazo reactive black 5 (RB 5) wastewater. CuSO 4 was found to be the most effective thermalcatalyst in comparison to ZnO. The color removal efficiency of RB 5 catalysed by CuSO 4 and ZnO were 91.55 % at pH 9.5 and 7.36 % at pH 2, respectively. From the UV-Vis wavelength scan, CuSO 4 catalyst is able to cleave the molecular structure bonding more efficiently compared to ZnO. ZnO which only show a slight decay on the main chemical network strands: azo bond, naphthalene and benzene rings whereas CuSO 4 catalyst is able to fragment azo bond and naphthalene more effectively. The degradation reactions of CuSO 4 and ZnO as thermalcatalysts in thermolysis process were compared.
