摘要
研究了利用二苯硫脲－甲基异丁酮泡塑振荡吸附富集Ａｕ、Ａｇ的条件，并采用金试剂－ＴＢＰ液珠萃取比色法测定地质样品中的金、银。方法的检出限：Ａｕ为０．５×１０－９，Ａｇ为５×１０－９。
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.
