Abstract:

This paper introduced a method for analyzing the chloridion content in soil by ion chromatography with water as the extracting agent. Soil samples could be extracted by deionized water in a water/soil ratio (v/w) as 10:1 with ultrasonic treatment for 30 min. Then the chloridion was seperated by anion exchange chromatography with KOH as elution buffer and detected by electrical conductivity detector. Results of accuracy and exactitude experiments showed this method could be used to treat various soil samples with different characteristics.
