Abstract: A solution is proposed for the safety of table salt by determining the content of various forms of chromium. The use of ultrasound for the formation of chromium acetylacetonate at room temperature and for the destruction of organic chromium compounds in brines and common salt was studied. A set of methods for the determination of chromium in common salt and brines has been developed, which makes it possible to determine chromium in various degrees of oxidation, as well as chromium, associated with dissolved organic substances. The correctness of the procedures was checked on the brine and salt samples by the "introduced-found" method, as well as by the analysis of the same samples by the developed and standard methods. Limit of detection of chromium 0.01 mg / kg.
Key words: ultrasound, table salt, safety, acetyl acetone, chrome in various degrees of oxidation
