Decoloration

The process of organic dye removal from various water solutions containing organic dyes and inorganic additives by DC diaphragm discharge has been studied in he so-called “negative part” of this discharge. The concentration of treated dye decreased almost exponentially to constant residual value. Th

The photo-oxidation of Rhodamime B was carried out in the presence of H2O2 using UV light. The effects of dye concentration, pH, H2O2 dose and irradiation time were studied. These parameters strongly influenced the degradation of the dye. As expected, the increase of initial dye concentration decrea
