Soil quality — Determination of perchlorate in soil using ion chromatography

This document specifies a method for the determination of perchlorate in soil and soil materials. Under the conditions specified in this document, a concentration as low as 0,1 mg/kg can be determined. The working range is restricted by the ion-exchange capacity of the separator column. Dilution of the water extracts to the working range can be necessary.
