Fotokatalytická degradace vybraných látek ve vodách

Abstract

This Bachelor’s thesis deals with photocatalytic degradation of 4-nitrophenol in aqueous solution in the presence of a catalyst ZnS-MMT. In the beginning there is an overview of organic and inorganic pollutants present in wastewater. In the next part basic definitions and concepts in the field of photochemistry are described. This is followed by a general description of the operation based semiconductor photocatalyst, there are also explained key concepts and definitions of photocatalysis. The experimental section describes the measurement procedures and results of photocatalytic degradation.
