On the Kinetics and Mechanism of the Thiourea

The thiourea dioxide–periodate reaction has been investigated under acidic conditions using phosphate buffer within the pH range of 1.1–2.0 at 1.0 M ionic strength adjusted by sodium perchlorate. Absorbance–time series are monitored as a function of time at 468 nm, the isosbestic point of the I2–I3– system. The profile of these kinetic runs follows either sigmoidal-shaped or rise-and
