Effect of MeOH and TBA on SMX degradation in Mn(II)/PAA/NTA process (a); degradation of SMX by Mn(III)-NTA alone and Mn(III)-NTA/PAA within 60 s (b); effect of EtOH on SMX degradation in Mn(II)/PAA/NTA process (c); degradation of PMSO and formation of PMSO2 in Mn(II)/PAA/NTA process (d). Experimental conditions: [PAA]0 = 0.2 mM, [NTA]0 = 25 μM, [Mn(II)]0 = [Mn(III)-NTA]0 = 5 μM, [MeOH]0 = [TBA]0 = [EtOH]0 = 100 mM, [PMSO]0 = 10 μM, [SMX]0 = 10 μM, pH0 = 6.5, T = 25 °C.
