In the presence of cetyltrimethylammonium bromide (CTA) perchlorates form a sparingly soluble compound. The analysis has proved that it is cetyltrimethylammonium per-chlorate. In the present work gravimetric, nephelometric and turbidimetric methods of determination of perchlorates have been worked out. Measurements can be made in the pH range from 1.5 to 11.5. For 5 to 20 mg of perchlorate the gravimetric...
