exposed to thiourea buffered solution (N1s = ± ) was two times higher than the value calculated for the discs soaked in carbamide buffered solution (N1s = ± ). These results indicated stronger attraction of thiourea to the platinum discs and correlated well with the differences in neutralization profiles displayed in Figure 2.
