This book looks at the development in the area of photocatalytic degradation of dyes using the latest photocatalytic techniques, for example by means of various nanoparticles, heterogeneous, and hybrid systems. Dyes are one of the major groups of pollutants and are widely used in a diverse range of industries. The toxic effects of organic dyes in waste water can have a great environmental impact, therefore there is significant interest and need to remove these dyes effectively and efficiently. This volume covers a plethora of basics on photochemistry of dyes and provides information on technological perspectives including reactor designs and process intensification. Since many industries release a significant amount of coloured effluents, which are toxic and difficult to remove by conventional methods, the comprehensive studies herein will contribute to helping reduce the impact of coloured effluents in waste water to the environment.  weiterlesen
