Mechanical milling Pharmaceutical drugs Photocatalysis Thermal activation ZnO powders. The optimal temperature and time of mechanoactivation are experimentally established. The degradation rate of Acetaminophen and Chloramphenicol increases with time of mechanical activation up to 30 min and then decreases. The ZnO powders annealed at 100 ☌ show highest photocatalytic efficiency and rate constant of dye degradation, which is due to the smaller size of nanocrystallites and their better developed surface. The changes in the studied material (phase composition, structure and particle size of the samples) and morphology have been investigated by means of X-ray diffraction and Scanning electron microscopy. The mechonoactivation is performed varying the atmosphere in air, or in suspension of ethanol and methanol. Commercial ZnO powders are activated thermally (annealed at different temperatures-100, 200, 300, 400 and 500 ☌ for 1 h) and mechanically (treated for 5, 15, 20, 30, 40 and 60 min). In this study we present photocatalytic purification of water from Acetaminophen and Chloramphenicol by ZnO upon UV-light illumination. 14953, 15960 Iordanova (19961997), 249 Isanovi (2006), 5275 Jelaa (2016), 3843 Kaneva and Ibroscheva (2015), 229 Kaneva (2016), 78.

Over the past few years, pharmaceutical drugs have been considered as emerging pollutants due to their continuous input and persistence in the aquatic ecosystem even at low concentrations.

Certain key indicators of the Bulgarian banking system have been examined for the period January 2007 – May 2015, which allows the outlining of the effects of the world crisis processes on the activity of banks in Bulgaria. In the second part of the paper, an analysis has been carried out of the development of the Bulgarian banking system under the impact of the global financial crisis and the eurozone debt crisis. Great importance has been attached to the detailed requirements for the banks’ capital adequacy assessment, the introduced five new capital buffers and the role of the stress-tests as a major instrument of risk management in banks. In the first part of the paper, an analysis has been made of the changes in the supervisory framework for the bank risks in the EU Member States, and particularly in Bulgaria, aiming at more efficient control and prudential supervision over the credit institutions. This research is dedicated to the development of the Bulgarian banking system in the period 2007-2015 under the impact of the global crisis processes.
