Microchimica Acta Aims and scope Submit manuscript

Summary

A method has been developed for the determination of small amounts of potassium perchlorate in admixture with potassium chlorate. The method involves preliminary decomposition of the potassium chlorate by boiling with concentrated hydrochloric acid, preparing a disc from the dried residue, and measuring its absorbance at 628 cm−1.

Zusammenfassung

Eine Methode zur Bestimmung kleiner Mengen Kaliumperchlorat in Gegenwart von Kaliumchlorat wurde ausgearbeitet. Sie beruht auf der vorhergehenden Zersetzung des Chlorats durch Kochen mit konz. Salzsäure, Herstellung einer Scheibe aus dem Trockenrückstand und Messung ihrer Absorption bei 628 cm−1.
