Abstract

Otpadne vode u postupku galvanizacije sadrže visoke koncentracije teških metala koje predstavljaju izravnu opasnost po ekosustav. Teški metali koriste se u postupku prevlačenja materijala, pri čemu nastaju prevlake određenih metala. Ukoliko se teški metali ne uklone iz otpadnih galvanskih voda, može doći do ozbiljnih posljedica po zdravlje ljudi i okoliš. Obrada otpadnih voda nastalih procesom galvanizacije može se provesti kemijskim, elektrokemijskim i biološkim metodama. U radu je kvantitativno ispitan uzorak otpadne vode na sadržaj Ni, Fe,Cu, NO3-, CrO4, i SO42-.

Abstract (english)

Abstract: Wastewaters in electroplating process contain high level concentration of heavy metals, and because of that, they present direct danger for ecosystem. Heavy metals are used in the coating process, which produces covers of certain heavy metals. If the heavy metals are not properly removed from galvanic wastewaters, that can lead to serious consequences for human health and environment. Treatment of wastewaters produced in electroplating process can be carried out with chemical, electrochemical and biological methods. In this paper, sample of wastewater was quantitatively tested for the presence of Ni, Fe, Cu, NO3-, CrO4 and SO42-.
