| Abstract: | First,the pure gold samples are resolved in aqua regia and matched with standard matrix.And then,the direct determination method of Fe,Ag,Cu,Pb,Bi and Sb in pure gold with inductively coupled plasma-atomic emission spectroscopy(ICP-AES) is established.The experiments reveal that comparing with GB/T 11066-89 analysis method,the ICP-AES method has the following characteristics: faster speed,higher accuracy and precision,lower detection limit. |
