New USEPA Cyanide Analysis Methods

The USEPA Administrator recently signed a Method Update Rule (MUR) approving new methods for analysis of NPDES wastewater samples. Six ASTM methods covering sampling, preservation and analysis of free, available and total cyanide are included in the MUR.

USEPA approval of ASTM D 7511-09e2 allows labs to analyse samples for total cyanide without a preliminary 2-hour acid distillation step. OI Analytical’s (USA) CNSolution 3100 Cyanide Analyser uses in-line UV digestion to dissociate metal-cyanide complexes and measure total cyanide in minutes by ASTM D 7511-09e2.
