摘　　要：复古金饰品是一种新型足金饰品,作为一种新产品,因其款式多样,硬度较高,可以满足人们的特色需求。为研究这种产品,实验中采用X射线荧光光谱法、ICP光谱法、火试金法、硬度仪对黄金样品进行了测试和研究。研究结果表明:复古金饰品因加工特性和杂质元素种类较多,又缺少合适的标准物质,X射线荧光光谱法分析结果不理想,可选用ICP光谱法和火试金法进行检测。硬度测试结果显示,复古金饰品硬度远高于普通足金。Vintage gold jewelry is a new type of pure gold jewelry,as a new craft and new product,it can meet people's special needs because of its diverse styles and high hardness.In order to study this product,the gold samples were tested and studied by X-ray fluorescence spectroscopy,ICP spectroscopy,fire assay and hardness tester.The results show that:due to the processing characteristics of retro gold jewelry and the variety of impurity elements,and the lack of suitable standard materials,X-ray fluorescence spectrometry analysis results are not ideal,ICP spectroscopy and fire assay can be used to detect.The hardness test results show that the hardness of retro gold jewelry is much higher than that of ordinary solid gold.
