DETERMINATION OF CERTAIN AROMATIC COMPOUNDS IN THE WASTEWATER
The extraction of hydroxybenzaldehyde of water – soluble polymers (polyethylene glycols PEG-2000 and PEG-5000) was study. The dependence between the concentration of the extractant and the characteristics of the distribution in two-phase system was installed. The optimal conditions of maximum extraction characteristic are defined. Methods of determination vanillins in aqueous solutions with diazotized polyurethane foam was developed. For chromaticity analysis applied appropriate software that can reliably and accurately automatically calculate analytical values. In work pioneered environmentally safe water-soluble polymers for the concentration and extraction of hydroxybenzaldehyde from aqueous media. On the basis of the results of the study and the developed methods, it is possible to recommend a set of measures to determine hydroxybenzaldehyde in the analysis of domestic and sewage water of various kinds of industrial enterprises.
