Chloride Analysis in Han-Based Liquid Propellants by Inductively Coupled Plasma Spectroscopy

Abstract

Inductively coupled plasma (ICP) spectroscopy was used to determine the chloride content of HAN-based liquid propellants in the parts per million (ppm) range with a detection limit of 1.5 ppm. Chloride is traditionally determined titrimetrically or gravimetrically with a typical precision of 0.01 weight percent (100 ppm). Samples of propellant as formulated and spiked with chloride ions were reacted with a known excess of silver. After the silver chloride precipitate was removed, the remaining silver in solution was analyzed by ICP. This excess metal reaction is necessary in ICP analysis because the instrument is not capable of monitoring emissions from chloride ions. ICP spectroscopy, Chloride analysis, HAN-based propellant.
