560 EXTRACTABLE CHLORIDE IN BOTANICAL MATERIALS - CHLORIDOMETER METHOD
Cl
Total Cl by 2% acetic acid extraction and determination by chloridometer.
Summary: This method quantitatively determines the amount of chloride (Cl) in an acetic-acid extract of botanical materials. It is based upon the electrometric titration of the extract with silver using an automatic colorimetric chloride titrator. Plant tolerance to chloride can be related to the concentration of chloride in the extract. The method has a detection limit of 0.01% and is generally reproducible within 8%.
