Abstract

Uklanjanje reaktivnih bojila iz otpadnih voda tekstilne industrije važno je zbog negativnog utjecaja obojene vode na okoliš i zbog nastajanja opasnih nusprodukata tijekom razgradnje u okolišu. Jedna od najučinkovitijih metoda obezbojavanja otpadnih voda je adsorpcija na aktivnom ugljenu. U okviru ovoga rada ispitan je utjecaj soli NaCl, kao uobičajenog dodatka u kupelj za bojadisanje, na proces adsorpcije. Postupak je proveden izotermnom adsorpcijom (45 °C) reaktivnog bojila Everzol Black B koncentracije 500 mg dm3 na aktivnom ugljenu (0,1 g), u vremenu od 15 min – 16 sati uz dodatak 1 mol dm3 NaCl. Dobiveni rezultati uspoređeni su s rezultatima dobivenim adsorpcijom na aktivnom ugljenu bez dodatka soli i ukazuju da dodatak veće količine soli pospješuje postupak adsorpcije, ubrzavajući sam proces, a adsorpcija bojila provedena je s izvanrednom učinkovitošću od 99,9 %.

Abstract (english)

The removal of reactive dyes from the wastewater of the textile industry is important due to the negative impact of colored water on the environment and due to the emergence of hazardous by-products during decomposition in the envionment. One of the effective methods of wastewater decolorization is adsorption on activated carbon. In this work, the influence of NaCl salt, as a commnon additive in the dye bath, was tested on adsorption process. Procedure was conducted by isothermal adsorption (45 °C) of the reactive dye Everzol Black B with a concetration of 500 mg dm-3 on activated carbon (0,1 g), in the time of 15 min – 16 hrs with addition of 1 mol dm-3 NaCl. The obtained results were compared with the results obtained by adsorption on activated carbon without the addition of salt and indicate that the addition of a larger amount of salt accelerates the adsorption process, accelerating the process itself and the dye adsorption was carried out with extraordinary efficiency of 99,9%.
