Abstract


It was determined calcium, magnesium, nitrites, nitrates, ammonium, chloride, dicarbonates, pH, hardness, total dissolved solids (TDS) and chemical oxygen demand (CODMn) of carbonated and uncarbonated mineral waters from Stâna de Vale sources (Bihor county). The experiments have been carried out during six months (november 2005 – april 2006) using both volumetric and photometric techniques. Some of results (Ca2+, Mg2+, Cl-, NO2-, NO3-, hydrogen carbonate, TDS) were compared with mean values of EU mineral water.

Keywords


mineral water; chemical composition; volumetric and photometric methods
