Water quality. Determination of available weak and dissociable (WAD) cyanide-Method using ligand exchange, flow injection analysis (FIA), gas-diffusion and amperometric detection
水质 有效弱可离解(WAD)氰化物的测定
BS ISO 20950-1:2018 specifies operationally defined methods for the determination of available WAD cyanide in various types of water such as drinking, ground, and surface, waters, and metallurgical processing tailings reclaim, heap leach barren, mill slurry tailings and leaching solutions, with cyanide concentrations from 5 µg/l to 2 000 mg/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 volume, thicker membrane, detector response, etc.Cross References:ISO 3696ISO 8466-1ISO 8466-2ISO 5667-3ASTM D6888ASTM D7728ISO 5725-2USEPA Method OIA-1677ISO/TR 19588:2017ISO 17690:2015ISO 2080:2008All current amendments available at time of purchase are included with the purchase of this document.
