| 摘 要： | 通过对火焰原子吸收分光光度计的燃烧器进行改进,即在燃烧头狭缝的两侧分别放置1块由耐火材料制成的挡板,从而有效地降低了燃烧头火焰波动。在采用FAAS法测定地质样品中的金时,通过使用不同挡板高度和调整两挡板间距离进行了对比实验;分析结果表明,对燃烧器的优化改进可以有效地提高测定结果的稳定性和可靠性,从而也可以降低FAAS法测定地质样品中金的检出限。

| Abstract: | A baffle made of fire-resistant materials is placed on both sides of the slit on the burning end, an improvement of burner of FAAS effectively reducing the volatility of the burner flame. A contrast test is carried out between different baffle heights and slit width when FAAS is used to determine gold in geological samples. The results show that the improvement can decrease the detection limit and improve the stability and reliability of the determination of gold sample results. |
