Bioallethrin degradation by photo-Fenton process in acetonitrile/water and aqueous β-cyclodextrin solutions

•Bioallethrin degradation was studied by photo-Fenton and modified photo-Fenton processes.•Bioallethrin is degraded by photo-Fenton in water, acetonitrile/water mixture and in aqueous solution of β-cyclodextrin.•The association constant of Bioallethrin to β-cyclodextrin was measured to be 1933 ± 300 M−1.•The degradation rate of Bioallethrin by photo-Fenton is similar in water than in an aqueous solution of β-cyclodextrin.
