| Abstract: | 1,3-Cyclopentanedione bis(4-methylthiosemicarbazone) monohydrochloride produces colored solutions with chlorate ions in strongly acid medium. The yellow color obtained has been used to propose a spectrophotometric method of C103? determination in the concentration range 0.5–6.0 ppm (molar absorptivity 1.26 × 104 liters mol?1 cm?1 at a wavelength of 397 nm). |
