Heterogeneous photocatalysis of metronidazole in aquatic samples

Metronidazole (MET) is a commonly detected contaminant in the environment. The compound is classified as poorly biodegradable and highly soluble in water. Heterogeneous photocatalysis is the most promoted water purification method due to the possibility of using sunlight and small amounts of a catalyst needed for the process. The aim of this study was to select conditions for photocatalytic removal of metronidazole from aquatic samples. The effect of catalyst type, mass, and irradiance intensity on the efficiency of metronidazole removal was determined. For this purpose, TiO2, ZnO, ZrO2, WO3, PbS, and their mixtures in a mass ratio of 1:1 were used. In this study, the transformation products formed were identified, and the mineralization degree of compound was determined. The efficiency of metronidazole removal depending on the type of catalyst was in the range of 50–95%. The highest MET conversion (95%) combined with a high degree of mineralization (70.3%) was obtained by using a mixture of 12.5 g TiO2–P25 + PbS (1:1; v/v) and running the process for 60 min at an irradiance of 1000 W m?2. Four MET degradation products were identified by untargeted analysis, formed by the rearrangement of the metronidazole and the C-C bond breaking.

Tritiated metronidazole and preparation method thereof

The invention belongs to the field of radioactive isotope labeling preparation, and particularly relates to tritiated metronidazole and a preparation method thereof. The preparation method includes: using 2-methyl-5-nitroimidazole as a raw material to react with N-iodosuccinimide to obtain 4-iodine-2-methyl-5nitroimidazole; under catalysis of palladium carbon, enabling 4-iodine-2-methyl-5nitroimidazole and tritium gas to be in tritium-halogen exchange to generate 4-3H-2-methyl-5-nitroimidazole; enabling 4-3H-2-methyl-5-nitroimidazole to react with ethylene oxide to obtain 4-3H-metronidazole. A synthetic product is purified through a prepared liquid phase to obtain4-3H-metronidazole with high specific activity (22.08Ci/g), high radiochemical purity (greater than or equal to 98%) and high chemical purity (greater than or equal to 98%). The tritiated metronidazole can be used as a radioactive tracer in studying absorption, distribution, metabolism and residue elimination of metronidazole in animal bodies.
