摘　　要：在湖南常德谢家岗多金属矿地质样品测试过程中,采用泡塑吸附-原子吸收测试方法,通过矿样焙烧、溶矿、泡塑吸附、分离、洗净、灰化、提取等前期处理,用原子吸收法在242.82 nm波长处进行Au的测定。与外部检测机构及内部的活性炭吸附法测定的金试样结果进行对比,误差在允许范围内,证明采用泡塑吸附-原子吸收测试方法进行金的测定,具有成本低、检测快速、结果准确、重现性好的特点。检测机构可以泡塑吸附原子吸收方法为主要测试方法,辅以活性炭吸附等方法进行验证,可以有效提高样品的测试效率并保证测试结果的准确性。During the geological sample testing process about Xie Jiagang polymetallic of Changde in Hunan,using the foam-atomic absorption test method,through the preliminary precessing of ore sample roasting,dissolving,adsorption,seperation,cleaning,carbonization,extractiong etc,then determine the gold by atomic absorption at 242.82 nm wavelength.Compared with the results of the gold sample determined by the external and internal testing institutions with the active carbon adsorption method,the error is within the allowable range,which proves that the foam-atomic absorption test method for the determination of gold has the characteristics of low cost,rapid detection,accurate results and good reproduction.Foam-atomic absorption method can be the main method for testing institutions,supplemented by activated carbon adsorption and other methods for verification,can improve the test efficiently and ensure the results accurately.
