Water quality. Determination of available free cyanide (pH 6) using flow injection analysis (FIA), gas-diffusion and amperometric detection Ingestion-build-81111 Calculation of mass and tolerances1 Scope This International Standard specifies methods for the determination of available free cyanide at pH 6 in various types of water (such as ground, drinking, surface, leachate, waste water, and metallurgical processing waste water) with cyanide concentrations from 5 g l to 500 g l expressed as cyanide ions in the undiluted sample. The range of application can be changed by varying the operation conditions, e. g. by using a different injection
