The extraction-spectrophotometric method for the determination of perchlorat-iones in explosives is studeed. This method is based on the extraction of perchlorate as an ion pair with brilliant green into organic solvent and measuring the absorbance of the organic phase at 640 nm. The influence of the various factors - pH of a solution, type of the solvent, reagent concentrations and standing time was investigated and optimum conditions were established. The effects of other cations and anions on the extraction were also studied.
