Abstract: The study established a method for gold content determination in cyanide solutions by activated carbon adsorption-flame atomic absorption spectrometry.The condition test determined that the maximum sampling amount is 200 mL,the minimum is 10.00 mL,the aqua regia is 50 mL for dissolution,the heat time is 30 min,the paper pulp thickness when filtered is 0.5-0.8 cm,the volumetric media is 5 % HCl.The precision of the method is below 5 %.The recovery rate of reference materials is 94.0 %-99.4 %.The accuracy and precision are both good.
