Iodinated pharmaceuticals, thyroxine (a thyroid hormone) and diatrizoate (an iodinated x-ray contrast medium), are among the most prescribed active pharmaceutical ingredients. Both of them have been reported to potentially disrupt thyroid homeostasis even at very low concentrations Here, UV-254 nm-based photolysis and photochem. processes, i.e., UV only, UV/H2O2, and UV/S2O82-, were evaluated for the destruction of these 2 pharmaceuticals. Approx. 40% of 0.5μM thyroxine or diatrizoate was degraded through direct photolysis at UV fluence of 160 mJ/cm2, probably resulting from the photosensitive cleavage of C-I bonds. While the addition of H2O2 only accelerated the degradation efficiency to a low degree, the destruction rates of both chems. were significantly enhanced in the UV/S2O82- system, suggesting the potential vulnerability of the iodinated chems. toward UV/S2O82- treatment. Such efficient destruction also occurred in the presence of radical scavengers when biol. treated wastewater samples were used as reaction matrixes. The effects of initial oxidant concentrations, solution pH, as well as the presence of natural organic matter (humic acid or fulvic acid) and alkalinity were also studied. These results provide insights for the removal of iodinated pharmaceuticals in water and/or wastewater using UV-based photochem. processes.
