Abstract

U radu je provedeno ispitivanje uklanjanja ukupnog organskog ugljika iz sintetske otpadne vode pripremljene otapanjem magenta ink jet bojila na bazi vode (Epson) u destiliranoj vodi ultrazvučnim ozračivanjem (20 kHz) vode. Ispitan je utjecaj vremena ozračivanja, snage ultrazvuka (30 – 150W) i pH vode na učinkovitost uklanjanja ukupnog organskog ugljika. Upotreba ultrazvuka utječe na smanjenje organskog ugljika iz otpadnih voda, posebice povećanjem snage ultrazvuka i duljim trajanjem ultrazvuka, a u kiselim otopinama (pH 2) još je više pospješeno uklanjanje organskog ugljika. S obzirom na dobivene rezultate koncentracija nitrata i sulfata u pročišćenim uzorcima ne može se tvrditi da ultrazvučnim ozračivanjem dolazi do razgradnje bojila.

Abstract (english)

In the paper was carried out examination of removal of total organic carbon from synthetic wastewater prepared by dissolving magenta inkjet dyes on water-based (Epson) in distilled water by ultrasonic irradiation (20 kHz) of water. It was examined the influence of irradiation, power ultrasound (30 - 150W) and the pH of the water on the removal efficiency of total organic carbon. The use of ultrasound in a reduction of the organic carbon from the waste water, in particular by increasing the power of the ultrasound, and longer duration of ultrasound, and in the acidic aqueous solution (pH 2) was further facilitated by the removal of organic carbon. Based on the obtained results, the concentration of nitrate and sulfate in purified samples can be argued that ultrasonic irradiation leads to the degradation of dyes.
