| Abstract: | The preparation of tri-n-octyl amine cotton and the condition of its adsorption of gold as well as gold desorption method are described.The FAAS method is employed for gold determination.The determination range of this method is 0.5-40g/t.Its RSD is 2.3%.The method has been applied to the determination of gold in chalcopyrite,and its result agreed with that of the traditional polyurethane from enrichment method.This method is quick and simple with good separation effect. |
