ИССЛЕДОВАНИЕ СВОЙСТВ ВОДНЫХ СИСТЕМ, СОДЕРЖАЩИХ ПРИРОДНЫЕ ОРГАНИЧЕСКИЕ ПРИМЕСИ

By using methods based on EPR and spectrophotometry (original method), the estimate of organic impurities to form complexes with ions of copper (II) in the model systems containing distilled water with organic acids (citric, salicylic, glutamic), as well as in drinking water of Yekaterinburg before and after the after-treatment on household filters. Features and characteristics are revealed to the research methods of organic impurities complexation with copper (II) at a final concentration of below 3 mg/liter in drinking water city. It is found that the natural organic impurities contained in the tap water of Ekaterinburg, have a high complexing activity which is 1,9 times higher than that of salicylic acid, but the removal of the organic impurities from the water in the filtering process, significantly alters the activity of the remaining organic impurities relative to the copper (II).
