Ion Chromatography with Electrochemical Detection for Hydrazine Quantitation inEnvironmental Samples

摘要

A method for the separation and detection of three common industrial and militaryhydrazines in environmental matrices has been developed. The ammonium bases of hydrazine, monomethylhydrazine, and unsymmetrical dimethylhydrazine are separated by ion chromatography. Detection of the analytes is achieved by pulsed amperometric detection in alkaline solution at a gold working electrode. The method presented provides a fast and cost-effective means of analyzing hydrazines in environmental samples.
