*2.7. Stability and Reusability of the Photocatalyst*

The stability of the catalyst in post reaction condition was investigated using XRD. Additionally for further confirmation the post reaction water sample was analyzed using MP-AES to detect the leaching of Ag+ and Zn2+ ions during the photocatalytic disinfection experiment [11]. Catalyst was recovered by centrifugation at 12,000 rpm for 30 min and dried at 80 ◦C and reused for the photocatalytic disinfection application. Unless otherwise mentioned all the experiments were conducted in triplicate.
