(a) Setup to determine different amount of current generated during plasma bombardment in different pH solution; (b) Visual test of H2O2 generation at different pH in the presence of titanyl ion after plasma bombardment; (c) Absorbance spectra of DI water before and after the Ar plasma treatment at different pH. To confirm the different concentration of H2O2 generation at different pH in the presence of titanyl ion.
