Abstract: A new method for the determination of trace gold in ore by flame atomic absorption after absorption by foam was proposed. The effect of
experimental conditions such as foam shape, processing methods, adsorption acidity, adsorption time and aqua concentration on the gold adsorption, and
determination sensitivity was discussed. Under the optimum conditions, the linear range in 0~80 μg/mL of gold concentration is good, regression equation is
y=+, correlation coefficient is , the recovery is 97 %~102 %, and the relative standard deviation (RSD) is %~ %(n=11). The method
