6 10 A REVIEW ON THE DEVELOPMENT OF INSTRUMENTAL METHODS FOR DETERMINATION OF THE PRECIOUS METALS L I Zhongxi, ZHOU Liping, FEN G Yuhuai ( N orthwest N onf errous Geological Research Instit ute, S haanxi Xian 710054, Chi na) Abstract : In this paper, the development of instrumental methods for the determination of the precious metals was reviewed. The applications wit h respect to spect rophotomet ry, elect romt ric met hods, Atomic absorption spect romet ry, atomic emission spect romet ry, inductively coupled plasmas mass spect romet ry, X2ray fluorescence spect romet ry and ot her met hods were presented. Simultaneously, a new designed non2dispersive atomic fluorescence spect rometer ( S K - 800) for determination of gold was int roduced simply.
