Abstract

In this paper, the possibility of purifying textile industry wastewater using metallurgical adsorbents: anode dust and waste moulding mixture was studied. The wastewater of the textile industry was simulated in such a way that a laboratory solution of copper and zinc ions was made and the competitive adsorption of the two ions was monitored. The obtained results indicated that the adsorption efficiency of both adsorbents is very high (52.3 to 94.8 %) with a slightly higher affinity towards copper ions. The experimental data were modeled by the Langmuir and Freundlich isotherm. The obtained results indicated that zinc adsorption takes place according to the Freundlich model, and copper according to the Langmuir model.
