چکیده انگلیسی
The present paper presents the study of the decolourisation of real textile effluent by constant current electrolysis in a flow-cell using a DSA® type material. The effect of using different anode materials (Ti/Ru0.3Ti0.7O2; Ti/Ir0.3Ti0.7O2; Ti/RuXSn1âXO2, where X = 0.1, 0.2 or 0.3) on the efficiency of colour removal is discussed. Attempts to perform galvanostatic oxidation (40 and 60 mA cmâ2) on the as-received effluent demonstrate that colour removal and total organic carbon (TOC) removal are limited. In this case the greatest degree of colour removal is achieved when anode containing 90% SnO2 is used. If the conductivity of the effluent is increased by adding NaCl (0.1 mol Lâ1) appreciable colour/TOC removal is observed. The efficiencies of colour and TOC removal are discussed in terms of the energy per order (EEO/kW h mâ3 orderâ1) and energy consumption (EC/kW h kgâ1 TOC), respectively. Finally, the extent of colour removal is compared to consent levels presented in the literature.
