APPLICATION OF THE SPECTROPHOTOMETRIC METHOD IN WATER QUALITY CONTROL

Zadatak ovog završnog rada je upotreba spektrofotometrijskih metoda u kemijskoj analizi vode. Naglasak je dat važnosti vode, te zbog čega je voda neophodna za život na Zemlji, fizikalno-kemijskim pokazateljima kvalitete vode, te zakonskojregulativi. Opisana je spektrofotometrija i spektrofotometrijske metode. Za provedbu eksperimentalnog dijela rada uzeti su uzorci vode sa pet različitih mjesta u gradu Slavonskom Brodu. Analiza se vršila u laboratoriju gradskog vodovoda. U uzorcima vode se određivao mangan, željezo, amonijak, nitriti, nitrati. Uporabom spektrofotometrijskih metoda se na vrlo brzo dobiju rezultati, te mogućnost brze reakcije u slučaju nezadovoljavajućih rezultata.The task of this final paper is the use of spectrophotometric methods in chemical analysis of water. Emphasis is placed on the importance of water, and why water is necessary for life on Earth, physico-chemical indicators of water quality, and legislation. Spectrophotometry and spectrophotometric methods are described. For the implementation of the experimental part of the work, water samples were taken from five different places in the city of SlavonskiBrod. The analysis was performed in the city water supply laboratory. Manganese, iron, ammonia, nitrites, nitrates were determined in water samples. The use of spectrophotometric methods gives results very quickly, and the possibility of a quick reaction in case of unsatisfactory results
