The pH of PGNO-treated DI water and phosphate buffer. (a) The pH of DI water monitored during and after PGNO injection. (b) The pH of potassium phosphate buffer (0.5 mM and 50 mM) monitored during and after PGNO injection. In (a) and (b), PGNO was injected for 50 min. Before PGNO injection, N2 was injected for 0, 10, 30, or 60 min to remove O2. All data points represent mean ± standard deviation of 3 replicate measurements.
