| 中文摘要: |
| 为消除金溶液中基体的影响，配制了金基体多元素标准溶液，采用ICP-AES法对此标准溶液中Ag、Cd、Cr、Cu、Fe、Ni、Pb、Zn元素浓度进行稳定性测试，并利用线性拟合法进行数据分析。结果表明，金基体多元素标准溶液在12个月内浓度无显著性变化，证明溶液在避光和15~30℃环境下可以稳定贮存。 |
| 英文摘要: |
| Standard solutions with multi-element gold substrate were prepared in order to eliminate the influence of gold substrate, ICP-AES was used to test the stability of Ag, Cd, Cr, Cu, Fe, Ni, Pb, Zn concentration, and linear fitting was applied for data analysis. The results showed that the gold substrate multi-element standard solutions were no significant change in concentration within 12 months. It proved that the solutions could be stored stably in the dark and 15~30℃ environment. |
