| Abstract: | The behaviour of preconcetration of Au and Ag DPTU(Biphenyl thiourea)MiBK loaded polyurethane foam and the determination of trace gold and silver in geological sample by Bead Extraction (employmg color development system of gold (silver)gold reagentTBPTOA are stadied. The detection limit of Au is 0510-9,Ag510-9,the Au RSD% =10916,Ag RSD%=923. |
