| Abstract: | The preconcentration and determination of trace Au in geological materials by polyurethane foam and ICP- AES were described in present paper. The recoveries were in the range of 94.4%~111.0%, The results were in agreement with the value of the certified reference materials and the RSD were3.2%~12.8%. |
