| 中文摘要: |
| 以电感耦合等离子体发射光谱仪(ICP-OES)为主检仪器,采用基体匹配,测定金含量为999‰999.95‰的高纯金饰品中银、铝、砷、铋、镉、钴、铬、铜、铁、铱、镁、锰、镍、铅、钯、铂、铑、钌、锑、硒、锡、碲、钛、锌等杂质元素含量(RSD≤10%),用差减法确定饰品中金含量。 |
| 英文摘要: |
| The ICP-OES is taken as the main testing equipment,by matrix matching,the impurity element content(RSD≤10%)in high purity gold jewelry(silver,aluminum,arsenic,bismuth,cadmium,cobalt,chrome,copper,iron,iridium,magnesium,manganese,lead,palladium,rhodium,ruthenium,antimony,selenium,tin,tellurium,titanium and zinc)are determined,then the gold content is determined by subtraction method. |
