Thermodynamic Studies of Orange G Dye Removal Using Prepared GO/Zno Nanocomposite

Abstract

The photocatalytic degradation of orange G dye was investigated utilizing a GO/ZnO nanocomposite. Hydrothermal techniques were used to make the nanocomposite. Orange G dye was removed using aqueous suspension solutions with various dye concentrations, as well as 0.15g/100mL of synthesized nanocomposite. To find the ideal condition for completing the dye removal procedure, a range of criteria were explored. Various variables have been investigated such as the influence of the semiconductor mass, dye concentration, light intensity, and temperature. In this research, ΔH＝-0.082 kJ/mol and ΔS＝－0.197 k J/(k·mol), and 61.185 kJ/mol respectively. The irradiation solutions were investigated using a UV-Vis spectrophotometer.
