A new kinetic-spectrophotometric method was developed for the determination of barbituric
acid. The method is based on its inhibition effect on the reaction between hydrochloric acid
and bromate. The decolorization of methyl orange by the reaction products was used to
monitor the reaction spectrophotometrically at 510 nm. The variable affecting the rate of the
reaction was investigated. The method is simple, rapid, relatively sensitive and precise. The
limit of detection is 7.9× 10− 7 M and calibration rang is 1× 10− 6–6.0× 10− 4 M barbituric ...
