Abstract
Cyclopentane-1,3-dione bis (4-methylthiosemicarbazone) monohydrochloride produces coloured solutions with bromate ions in perchloric acid medium. The yellow colour obtained (molar absorptivity 1.8×104 1.mol−1.cm−1 at a wavelength of 400 mm) has been used for the spectrophotometric determination of trace amounts of bromate.Keywords
