Primjena naprednih oksidacijskih postupaka na bazi Fentonovog procesa za oksidaciju prirodnih organskih tvari u podzemnoj vodi

Primjena naprednih oksidacijskih postupaka na bazi Fentonovog procesa za oksidaciju prirodnih organskih tvari u podzemnoj vodiAn application of heterogeneous Fenton-type catalyst was investigated for the degradation of natural organic matter from two sources: model humic acid solution and natural groundwater from town Osijek area. For this purpose, supported iron catalysts were prepared by impregnation of different iron forms (Fe(III), Fe(II), FeOOH) on support materials. Different supports were evaluated: natural zeolite clinoptilolite and two commercial types of activated carbon, Hidraffyn 30N and Silcarbon K835. The aim of this study was to investigate the performance of heterogeneous Fenton processes and compare them with the corresponding homogenous Fenton process. The effect of the most relevant operating conditions (catalyst concentration, H2O2 concentration, pH) was estimated. When process was conducted in optimal conditions, homogeneous catalyst showed slightly higher efficiency when compared to the corresponding processes applying heterogeneous catalyst. Moving away from optimal conditions, the effectiveness of homogeneous processes was rapidly decreased, while the efficiency of heterogeneous processes was more constant and processes were less sensitive to the change of process parameters and in these conditions the heterogeneous processes gave similar or even better results.
