Popis
BS EN ISO 17380:2013
This standard BS EN ISO 17380:2013 Soil quality. Determination of total cyanide and easily liberatable cyanide. Continuous-flow analysis method is classified in these ICS categories:
- 13.080.10 Chemical characteristics of soils
This International Standard specifies a method for the photometric determination of the total cyanide and easily-liberatable cyanide content in soil using automated distillation/continuous-flow analysis.
The International Standard applies to all types of soil with cyanide contents above 1 mg/kg on the basis of dry matter, expressed as cyanide ion.
NOTE 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.
