摘　　要：研究了物理性能和灼烧残渣量不同的甲、乙两种聚氨酯泡沫塑料对微量金发射光谱特征谱线(267.6nm)背景干扰的问题。结果表明,通过NaF预处理的聚氨酯泡沫塑料,对金发射光谱特征谱线背景的干扰最小,从而,相对提高了化探样品中微量金分析测试的灵敏度和准确度。The interference of 2 sorts of PUFP with different physical properties and residuals after roasting in gold emission characteristic spectrum was studied. As a result, PUFP pretrealed by NaF has least background disturbing of gold emission characteristic spectrum. Therefore, it relatively improves the precision and accuracy for the determination of trace gold in geochemistry samples.
