The effect of various parameters such as pH, initial concentration of pollutant, catalyst dose, oxidant, and time variation were studied. The determination of the best catalyst was studied amongst the four catalysts (TiO2, ZnO, PSA and SSA) .The kinetics of degradation of isooctane was also studied. The results showed that TiO2 was the best catalyst with a degradation rate of 57%. Also, the optimum conditions for the degradation of the isooctane were; 50mg/L of initial concentration, pH 8 and catalyst dose of 4.0g/l. The kinetics analysis for the degradation of isooctane revealed that it follows pseudo – first‐ order reaction kinetics. The Langmuir – Hinshelwood model showed a better fitting with reaction rate and adsorption equilibrium constants of 3.0 mg/L.h and 1.53 × 10‐3 L/mg respectively and the regression was 0.979.
