(a) Kinetic profiles of transient absorption at 700 nm after the 266 nm laser pulse excitation of I, S, and S + I solutions; (b) kinetic profiles of transient absorption at 350 nm after 266 nm laser pulse excitation of I and S + I solutions; (c) decay of sulfite in UV/S and UV/S + I in the absence of PFAS; and (d) lifetime of eaq in UV/S + I at varied solution pH. Conditions: Na2SO3 (S, 10 mM), KI (I, 2 mM), and pH 12.0.
