Abstract
U ovom su radu spektrofotometrijski i kromatografski proučavani pojedini kemijski parametri zdravstvene ispravnosti vode koji uključuju praćenje koncentracije kalcija, magnezija, kalija, natrija, željeza, mangana, fosfora, klora i fluora u uzorcima konzumne vode iz vodovodne mreže u Osijeku. Promatrana voda uzorkovana je na 6 različitih lokacija (tri blizu Vodovoda i tri udaljene od Vodovoda). Spektrofotometrijskom analizom određivane su koncentracija iona mangana i željeza. Drugi dio rada obuhvaćao je analizu konzumne vode ionskom kromatografijom. Određivale su se i uspoređivale koncentracije pojedinih aniona i kationa. Cilj istraživanja bio je praćenje koncentracije ispitivanih kationa i aniona u određenom vremenskom periodu te uspoređivanje dobivenih vrijednosti sa zakonskim regulativama. Kako bi se upotpunilo istraživanje, određivana je i pH vrijednost navedenih uzoraka. Dobiveni rezultati ispitivanih parametara nisu pokazali značajnija odstupanja od zakonom propisanih vrijednosti. Rezultati pokazuju veće koncentracije aniona i kationa kod udaljenih lokaliteta zbog starih vodovodnih cijevi kojima se distribuira voda.
Abstract (english)
In this paper, certain chemical parameters of water quality which include monitoring of calcium, magnesium, potassium, sodium, iron, manganese, phosphorous, chlorine and fluorine concentration, were studied in the drinking water samples from the water supply network in Osijek by spectrophotometric and chromatographic analysis. The observed water was sampled in 6 different locations (three near the Water utility company and three away from the Water utility company). Spectrophotometric analysis was used to determine the concentration of manganese and iron ions. The second part of the work included analysis of drinking water with ionic chromatography. The concentrations of certain anions and cations were determined and compared. The aim of this research was to monitor the concentration of the investigated cations and anions in a given time period and compare the obtained values with the legal regulations. In order to complete the study, the pH value of the samples was also determined. The obtained results of the examined parameters did not show significant deviations from the statutory values. The results showed higher concentrations of anions and cations at locations far away from Water utility company because of the old water pipes used in water distribution.
