**4.6 Effect of various other catalysts being studied**

The non catalytic wet oxidation experiments were carried out on pure polyamide beads at temperature of 100 °C using potassium permanganate oxidation reagent for various durations. The observations at 50, 75 and 100°C are as shown below in **Figure 9**.

Further catalytic wet oxidation experiments were carried out on pure polyamide beads using 30% Hydrogen peroxide with ferrous sulphate catalyst for various durations. The observations at 50, 75 and 100°C are as shown below **Figure 10**. Further membrane performance studies are being planned to evaluate flux and salt rejection.
