Search for: [Abstract = "The source of UV\-C radiation was a lamp emitting a wave of light with a length of \? = 264 nm, placed directly above the layer of the samples wastewater. The sodium percarbonate Na2CO3 1.5 H2O2 doses were determined on the basis of stoichiometric calculation. Ratio of iron ions to the hydrogen peroxide released in reaction was\: 0.5\; 0.4\; 0.3\; 0.2\; 0.1. Before and after the oxidation process, COD and TOC value were determined and as well as concentrations of selected PAHs."]
