ANALYTICAL METHODS APPLICATION IN DETERMINATION OF PHYSICO-CHEMICAL PARAMETERS OF WATER

Zadatak ovog završnog rada je praćenje fizikalno-kemijskih parametara kakvoće vode. Voda je najzastupljenija tvar u građi svih živih bića pa se može reći kako je voda život. U završnom radu opisan je nastanak vode, kakvoća, kemijski spoj, zakonske regulative, vodoopskrba te fizikalno kemijska analiza. U eksperimentalnom dijelu rada analizirani su uzorci vode u ulazu u vodoopskrbni sustav te nekoliko drugih lokacija u Vukovarsko-srijemskoj županiji. Analiza se vršila u internom laboratoriju Vinkovačkog vodovoda. U uzorcima vode se određivala pH vrijednost, mutnoća, mangan, amonijak, nitriti, nitrati, fosfati, KMnO4, vodljivost, slobodni klor, željezo. Analiza vode se vršila kako bi se utvrdila njena ispravnost za ljudsku konzumaciju, je li zdravstveno ispravna i je li kemijski sastav vode unutar parametara koji su propisani Zakonom o vodi za ljudsku potrošnju (NN 56/13, 64/15, 104/17, 115/18), jer se ta ista voda transportirana do krajnjeg potrošača putem vodoopskrbne mreže.The task of this final work was to monitor physical-chemical parameter of water quality. Water is the most represented substance in the structure of all living beings, so it can be said that water is life. In this work is explained emergence of water, quality, chemical compund, legal regulations, water supply and physical-chemical analysis. In experimental part of this work we have analyzed samples of water at the entrance of water supply system and few other locations in Vukovarsko-srijem county. The analysis was performed in internal laboratory of the Vinkovci waterworks. In samples we determined pH value, temperature, fuzziness, manganese, ammonia, nitrites, nitrates, phosphates, KMnO4, conductivity, free chlorine, iron. Water analysis was performed to determine its correctness for human consumption, is it healthy, and whether the chemical composition of water is within the parameters that are prescribed by water Law for human consuption (NN 56/13, 64/15, 104/17, 115/18), because that same water is transported to the final consumer via the water supply network
