| 摘 要： | 在野外交通不便和无电力条件下，应用泡塑富集-硫代米蚩酮微珠萃取比色法，实现了5～1200ng/g金的测定，结果与室内化学光谱法比较，无明金样品的相对误差可控制在60％以内，含明金样品的相对误差基本在100％～500％，可以满足化探找金及异常查证的要求。方法能有效地指导化探找金工作。

| Abstract: | A method for the determination of gold in field with plastic foam adsorption-TMK extraction-microbead colorimetry was developed. Comparing with in-door chemical-spectrometry, the relative error of the method was less than 60% for the samples with 5-1200 ng/g Au and without grained (bright) Au, and about 100%-500% for the samples with grained (bright) Au. The method satisfies the requirements for Au geochemical exploration and Au abnormal inspection in field. |
