EVALUATION OF BROMINE, MINERALS AND SOLIDS MATERIALS IN OZONE-OXIDIZED AQUEOUS SOLUTIONS

Abstract

In this study, was evaluated the effectiveness of ozone in oxidation of metals and oxidation of organic matter was evaluated in aqueous solutions. The properties of nine samples of the most traded local bottled water in the local markets in Baghdad city were studied for three different months. This research was conducted to determine the suitability of water for drinking and it was found through laboratory tests conducted on the wide samples that some samples contain results within the permissible limit and others contain results outside the permissible limit specified by the World Health Organization and the Iraqi Ministry of Health. Acidity function and electrical conductivity for nine samples during the three months (February, April and August) came within the permissible and the samples from (1 to 9) It came within the permissible limits for turbidity which is (5NTU). The total hardness for samples (3,4,7,8,9) higher than the standards set by the Iraqi government, which is (176 mg/l). The laboratory tests of the samples proved that they contain dissolved solids within normal limits, which are (150-500 mg/l). samples (3, 4, 7, 8 and 9) have a significant increase in the calcium ion and all samples contained normal percentages of potassium and bromine, except for (sample 9). The nine samples came within the acceptable limits for fluoride.
