New U.S. EPA Cyanide Analysis Methods
August 23, 2010
On August 6th, 2010 the U.S. EPA Administrator signed a Methods Update Rule (MUR) proposing new test procedures for analysis of pollutants under the Clean Water Act. Six ASTM Methods covering sampling, preservation and analysis of free, available, and total cyanide were included in the MUR.
Labs will now be able to analyze NPDES wastewater samples for total cyanide without a preliminary 2 hour acid distillation step by following ASTM Method D 7511-09. The CNSolutionÔ Cyanide Analyzer uses in-line UV digestion to dissociate metal-cyanide complexes and measure total cyanide in minutes by ASTM D 7511-09.
