quality of mineral water, selective ion-exchange column

Sažetak
The quality of mineral water is conditioned by a number of factors, primarily the quality of water in the water source. The aim of this study was to determinate content of Ni2+ and Mn2+ ions in the mineral water, after treatment by selective ion- exchange column. The primary objective of investigated technological process was optimal performance of the column, during the processing of water, so that the content of Ni2+ and Mn2+ ions in the mineral water, after treatment reduce to allowable concentration, and the concentration of Mg2+ ions in the mineral water decreases insignificantly, and thereby the cost of water treatment are not increased. Also, during the study, was determined the effect of application of ion - exchange columns in the physico-chemical water parameters, such as turbidity of the water, the water hardness and pH value. The results showed a statistically significant difference (p < 0, 01) in the content of Ni2+ and Mn2+ ions before, and after treatment, so that the mean concentration of nickel in water before processing is 0, 187359 mg/l, and after the treatment, this value is 0, 015600 mg/l. For the Mn2+ ion concentration value before processing is 0, 113294 mg/l and after treatment this value was 0, 008206 mg/l. It should be noted that changes in the concentration of Mg2+ ions there is no statistical significance, before treatment was 388, 59 mg/l, and after treatment 383, 80 mg/l.
