Effect of radical-hole scavengers on the degradation rate of RhB (7.5 µM) by using TPPS (5.14 µM) at pH 3.0: blue – 1,4-benzoquinone, black – NaI, red – no scavenger, green – t-BuOH; orange – NaN3. Conditions: irradiation with Xe lamp (λ > 400), aerated aqueous solutions, stirring at 800 rpm, T = 298 K, Scavengers concentration: 10 mmol L‒1.
