This standard mainly uses ion chromatography technology to detect the cyanide content in electroformed gold products. This standard is suitable for the determination of cyanide content in electroformed gold products not less than 0.5 μg/g. The main technical contents of this standard include: sample preparation, sample solution preparation, cyanide extraction, calibration solution preparation, calibration curve construction, sample testing, result calculation and presentation, precision, etc.
