| 摘 要： | 云锦妆花缎是云锦中的高端产品，其中的扁金线的金层含金量一直没有检测方法。采用王水溶解云锦扁金线，进行ICP-AES法测定主成分金，次成分银、铜，按照金在检测的所有主要金属元素总和的相对占比来计算含金量。方法精密度分别为金13.1%~16.5%；银2.69%~6.54%；铜5.58%~9.92%，加标回收率分别为金96.5%~98.0%、银97.4%~100.0%、铜90.4%~101%。

| Abstract: | Satin of brocade-Zhuang hua is a high-end product in the cloud brocade, in which the gold content of the flat gold line has not been detected. The gold line of cloud brocade line was dissolved with aqua regia. Then ICP-AES method was used to determine the content of gold, silver, and copper. The gold content was calculated according to the relative ratio of the sum of all the main metal elements detected. The precision of the method was 13.1%~16.5% for gold, 2.69%~6.54% for silver, 5.58%~9.92% for copper, respectively. The standard recovery rate is 96.5%~98.0% for gold, 97.4%~100.0% for silver, and 90.4%~ 101% for copper, respectively. |
