Method 9015: Metal Cyanide Complexes in Waters and Waste ...

2.1 For aqueous samples containing 0.2 200 mg/L metal cyanide complexes, dissolved metal cyanide complexes are separated and quantified using anion exchange chromatography coupled with UV detection. For solid waste samples, the alkaline extraction procedure described in Method 9013 is necessary prior to chromatographic analysis of the
