Figure 3.
Formation of photoproducts from direct phototransformation of 2,6-DBP (aqueous solution, 80 μmol/L) with different time. Irradiated samples were analyzed by a HPLC-LTQ-Orbitrap and products were quantified with the internal standard method. P1, P2 are tetrabrominated products, P3-P5 are tribrominated product, P6 is monobromo-dihydroxybenzene. The symbols and error bars represent the mean and SD of three replicates. The calculated different product yields with reaction time are listed in Table S1.
