The aim of the master thesis is based on the flexographic printing field with the purpose to investigate the efficiency of Fenton process for treatment of Magenta flexographic dye, as well as to investigate the impact of various process conditions. Fenton process is very efficient in the degradation of various kinds of dyes. It is based on the addition of Fenton reagent, a mixture of hydrogen peroxide and iron ions, with the generation of hydroxyl radicals. Particles of nano-zero valent iron were used were used as a catalyst in Fenton process. The “green” synthesis of nanomaterial was carried out using fallen leaves of oak tree that grew in Fruška Gora National Park. Decolorization efficiency of printing dye aqueous solution was performed by series of experiments on the JAR test apparatus.
