The palladium nitrate with magnesium is suitable for measurement of Cr, Cd, and Sn. 硝酸钯加硝酸镁在测量铬、镉、锡时效果较好,且受硝酸影响小。
The ashing temperature is raised to 1400 ℃, and the matrix effects can be eliminated by using palladium and nickel nitrate mixed matrix modifier. 以钯和硝酸镍混合溶液做基体改进剂,提高灰化温度至1400℃,消除了样品中大量基体对测定锗的干扰。
Palladium nitrate was used as a matrix modifier to eliminate the interference. Slurry stability and the influences of the matrix modifier, ashing/ atomization temperature and coexistent ions on analytical signals were investigated in detail. 研究了悬浮剂、试样粒度、基体改进剂、灰化/原子化温度和共存金属离子对分析信号的影响。
