For quantitative analysis of perchlorate in capsules and solutions it has been proposed acidometric determination of perchloric acid in eluate after the use of cation exchangers. The comparison was made with colorimetric method of perchlorate determination after ion pairing with methylen blue which is extracted with chlorophorm and shows the maximum absorption at 655 nm. As an alternative method it has been used flame photometry of cations of these salts. The worked-out method with ion exchangers is recommended as a very suitable due to speed and simplicity of work and accurate and reproducible results.
