STUDIES ON THE DETERMINATION OF PHYSICOCHEMICAL PARAMETERS IN MINERAL WATER (BORCUT – VALEA PEȘTILOR) (I)

Abstract

The paper presents studies conducted to determine physicochemical parameters such as Cr, Ni, Mo, Cu, Zn, Ca2+, Mg2+, Br2, P, CaCO3, pH, Ec, TDS in mineral water (borcut) from Vișeu de Sus, Valea Peștilor. The experimental determinations were carried out using the Nikel Low Range Photometer, the Photometer for Boilers and Cooling Towers HI83305, as well as specific photometers for the proposed determinationswithin the study. The obtained results are: 4 μg/L Cr6+; 10 μg/L CrO4 2- and 9 μg/L Cr2O7 2-; 0.327 mg/L Ni, 0.1 mg/L Mo6+, 0.308 mg/L Cu, 1.06 mg/L Zn, 170 mg/L Ca2+, 52 mg/L Mg2+, 0.13 mg/L Br2, 0.2 mg/L P, 364 mg/L CaCO3, pH = 7.05 at 21.90C, EC = 1.99 and TDS = 1 ppt. Groundwaters are more mineralized than surface waters, and the deeper the water layer, the higher the degree of mineralization; the solubility of heavy metals depends on soil acidity, and for ions with the same valence, the retention energy increases with atomic mass.
