Nitrate content in the groundwater of Belarus has increased dramatically due to intensive use of nitrogen fertilizers in agriculture. Research performed during the post-Chernobyl period showed that the increased incidence of thyroid cancer is affected both by the level of nitrates in the groundwater ...

Bimetallic (Pd/Cu) catalysts supported on alumina were used for the degradation of nitrates in water.The reduction temperature strongly affects the surface and oxidation states of the metals on the catalysts.These significant changes were characterized by FT-IR,XPS,TEM with EDX and H_2 chemisorptio...
