Abstract
The thionine photoreduction kinetics in film of polyvinyl-alcohol is proposed to describe as the consecutive reaction with one equilibrium stage: (formula given in paper). To given scheme the values of k2 = (3,60 ± 0,26)•10-3 s-1 and k3=(2,93 ± 0,56)•10-3 s-1 are determined. The values of k1 constant demonstrate the linear dependence on laser intensity.
