D4282-02 Standard Test Method for Determination of Free Cyanide in Water and Wastewater by Microdiffusion
| Published By | Publication Date | Number of Pages |
| ASTM | 2002 | 6 |
1.1 This test method covers the determination of free cyanides in waters and wastewaters. Free cyanide is here defined as the cyanide which diffuses as cyanide (HCN), at room temperature, from a solution at pH 6.
1.2 This test method does not include complexes that resist dissociation, such as hexacyanoferrates and gold cyanide, nor does it include thiocyanate and cyanohydrin.
1.3 This test method may be applied to water and wastewater samples containing free cyanide from 10 to 150 ?g/L. Greater concentrations may be determined by appropriate dilution.
1.4 This test method has been fully validated by collaborative testing as specified by Practice D 2777.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 8.6, 8.9, Section 9, and 12.2.1.
