Abstract
Visoka koncentracija nitrata u vodi, kako u površinskim tako i u podzemnim vodama, posljedica je geološkog sastava tla ili antropološkog djelovanja. Povećane koncentracije nitrata u vodi ozbiljan su problem za zdravlje ljudi uzrokujući rak probavnog sustava i druge anomalije. Koncentracije nitrata veće od 50 mg/l mogu dovesti do bolesti zvanom methemoglobinemija kod djece do šest mjeseci starosti hranjena dojenačkom formulom. Nadalje, prisutnost nitrata u vodonosnicima, može utjecati na... More eutrofikaciju što uključuje i rast algi te smanjenje otopljenog kisika. Prirodna i umjetna gnojiva koja se koriste u ishrani bilja, proizvodnja detergenata, nekontrolirani ispust otpadnih voda u okoliš te industrijski otpad, glavni su izvori nitrata u vodi. Nitrati su stabilni, dobro topivi ioni koji se teško uklanjaju konvencionalnim metodama kao što su koagulacija, flokuacija, mekšanje vapnom ili adsorpcija. Ionska izmjena pokazuje zadovoljavajuće rezultate te je iz toga razloga najčešće korištena metoda za uklanjanje nitrata. Ovim radom ispitana je mogućnost uklanjanja nitrata iz vode primjenom komercijalnih ionskih izmjenjivača: Duolite A7 i Relite A490. Ispitan je utjecaj početne koncentracije nitrata (10, 50 i 100 mg/l), kontaktnog vremena (15 min – 24 sata) i mase ionskog izmjenjivača (0,1 – 0,6 g). Less
Abstract (english)
High concentrations of nitrates in the water, both in surface and in groundwater, is a consequence of the geological composition of the soil or human activity. Increased concentrations of nitrate in drinking water is a serious hazard to human heath, causing abnormalities such as cancerous growths in human digestion system. Nitrate concentrations higher than 50 mg/l can lead to disease called methemoglobinemia in children under six months of age fed with infant formula. Furthermore, the... More presence of nitrate in aquifers can stimulate eutrophication, which compromise the growth of algae and depletion of dissolved oxygen. Natural and chemical fertilizers in crop production, detergent manufacturing, uncontrolled land discharge of municipal wastewater, and industrial wastes have been identified as the main sources of nitrate in water sources. Nitrate is a stable, highly soluble ion that is difficult to remove by conventional water treatment methods such as coagulation, flocculation, lime softening or surface adsorption processes. Ion exchange is the most widely employed procedures used for removing nitrate. In this research the possibility of removing nitrates from water was examined by using commercial ion exchangers: Duolite A7 and Relite A490, respectively. The influence of the initial concentration of nitrate (10, 50 and 100 mg/l), the contact time (15 min - 24 hours) and the mass of the ion exchanger (0,1 to 0,6 g) was also examined. Less
