Abstract
Oxidation of Cr(III) during sonication in carbonated aqueous solutions saturated with CClO4 leads to the quantitative formation of Cr(VI) and provides a simple and rapid method for spectrophotometric chromium determination with 1,5-diphenylcarbazide. The key to this method is the production of chlorine radicals when aqueous solution saturated with CClO4 is exposed to ultrasonic waves of 40 kHz. The effects of sonication period, CClO4 solution volume, acidity, and interferences were discussed. The time required for a single determination is lower than 2 min. The relative standard deviation obtained for aqueous solutions with 1 µg of Cr was <2% (N = 10) and the calculated detection limit (3σ) was 5 ng of Cr.
