Abstract

ISO 17380:2004 specifies a method for the photometric determination of the total cyanide and the easily released cyanide mass fraction in soil using an automated-distillation continuous-flow analysis.

ISO 17380:2004 applies to all types of soil with cyanide mass fractions above 1 mg/kg on the basis of dry matter, expressed on the basis of the cyanide ion.

Sulfide concentrations in the sample higher than 40 mg/kg dry matter cause interference. This effect can be recognized by the split peaks and as a slow decrease of the detector signal and can only be prevented by diluting the sample extract.
