Levin, P. P.; Brzhevskaya, O. N.; Nedelina, O. S. published the artcile< Kinetics of hydrated electron reactions with phosphate anions: a laser photolysis study>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is hydrated electron decay kinetics photolysis sodium pyrenesulfonate phosphate anion.
The decay kinetics of hydrated electron (eaq-) formed upon photolysis of aqueous solutions of sodium pyrene-1,3,6,8-tetrasulfonate at λ = 337 nm in the presence of phosphate anions (up to 2 mol L-1) was studied by nanosecond laser-pulse photolysis in a wide range of pH (3.5-10) and ionic strength (I, up to 2 mol L-1) values. At high pH values, where the HPO42- ions dominate, the eaq- decay kinetics depends only slightly on phosphate concentration (rate constant for the reaction is at most 2·105 L mol-1 s-1). The H2PO4- ions react with eaq- at a rate constant of 2.8·106 L mol-1 s-1 (I = 0), which increases linearly with the parameter exp(√I/(1 + √I)) in accordance with the Debye-Hueckel theory. The rate constant for quenching of eaq- by H3PO4 at pH ≤ 4 decreases linearly with the parameter exp(√I/(1 + √I)) due to the secondary salt effect and equals 1.6·109 L mol-1 s-1 at I = 0. The logarithm of the rate constant for quenching of eaq- by phosphates is linearly related to the number of the O-H bonds in the phosphate mol.
