Resumen: Cyanides may be present in soil as cyanide ions and as complex cyanides. They can be determined as easily-liberatable cyanide or as total cyanide. Complex cyanide can be calculated by subtracting the easily liberatable cyanide result from the total cyanide result. This International Standard specifies a method for the photometric determination of the total cyanide and easily-liberatable cyanide content in soil using automated continuous flow analysis (CFA). The continuous flow analysis method uses an automated dosage of the sample into a flow system (manifold) where the analytes in the sample reacts with the reagent solution on their way through the manifold. The reaction product is measured in a photometric detector. This 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.
