Phosphoric acid and phosphate solutions

Flash photolysis [26] and pulse radiolysis [27, 28] studies were carried out in phosphoric acid solutions. H2P04, HPO4 - and PO4 were identified but the evaluated absorption coefficients and acid-base equilibria seemed smaller and slightly confused, respectively. However, the accepted molar absorption coefficients and acid-base equilibrium of these transients have been established as follows [29]. 

Pulse radiolysis study on the concentrated phosphoric solutions were reported and H2P04 radical formation was detected. Again, two formation
