Authors: Ustinova M. N., Zhunusov N. S.

The growth of the pharmaceutical industry inevitably leads to an increase in the concentration of organic pollutants in environmental objects. The problem of inactivation of such pollutants and water treatment is extremely urgent. The aim of this work was to use combined chemical methods of destruction of tetracycline, as one of the most commonly used antibiotics. The destruction of the active substance of tetracycline under UV irradiation, UV irradiation in the presence of hydrogen peroxide, and UV irradiation in the presence of hydrogen peroxide and ferrous iron ions was studied.

Rapid Determination of Tetracyclines in Milk by the Method of Mass Spectrometry High Resolution

Authors: Amelin V. G., Amelin A. I.

The method of determination of tetracycline antibiotics (tetracycline, chlortetracycline, oxytetracycline, doxycycline) in the milk of methods HPLC-MS/MS/MS and HPLC-QTOF-MS, with a simple and rapid sample preparation. The ranges defined concentrations of tetracyclines in milk sample of 1 g was 1–200 μg/kg. Relative standard deviation of the results of the analysis does not exceed 7%. The analysis duration 30–40 minutes.
