| Abstract: | Determination of trace Au in environmental samples by graphite furnace AAS was discussed. The agua regia was used to dissolve industrial solid waste, foam plastics was used to remove interference element, thiourea was used as release agent, then Vc reduction was carried out, at last graphite furnace AAS was used to determine trace Au. This method is simple, rapid, and has high sensibility, the detection limit can achieve 0.3 ng/g, so its precision and accuracy can meet national standard. |
