The Determination of Chlorate in Potassium Perchlorate Pyrotechnic Material by Specific Ion Electrode

摘要

A method for the determination of chlorate ion in potassium perchlorate was developed. The analytical method utilized a reduction of the chlorate ion to the chloride ion with ferrous ammonium sulfate. The chloride ions produced by this reduction step were then determined with a specific ion electrode technique. The amount of chlorate ion was determined by calculating how much chlorate ion was represented by the analyzed chloride ion making an appropriate adjustment for the amount of free chloride ion found in the potassium perchlorate and deionized water.
