Abstract

The reaction of chromium (VI) ion with Methilene Green basic dye in the solutions of hydrocloric acid has been studied. The formed ionic associate is extracted by bensole from pH 1.0–1.0 M HCI solutions. The optimal concentrations of basic dye is 3.21·10-3–4.8·10-3M. The range of determined concentration is 0.125–5.0 mcg Cr/mL ($\overline{\epsilon}_{640}$= 65000 L· mol-1· cm-1). The method was used for the determination of small amounts of chromium in milk, sour cream and curds.
