本文研究了以流动注射进样的ICP-AES分析方法和NaCl的基体效应。0.25-2.5%NaCl对11个元素的影响结果表明,FI进样可克服常规连续雾化的信号漂移,从而改善了测量精度。不同功率下的NaCl基体的影响不同。结果表明,NaCl的基体效应主要存在于气溶胶微粒在ICP中的蒸发—原子化—激发过程。
In this paper, flow injection injection ICP-AES and matrix effects of NaCl were studied. Effect of 0.25-2.5% NaCl on Eleven Elements The results show that FI injection improves signal measurement accuracy over conventional continuous atomization signals. The effects of NaCl matrix at different powers are different. The results show that the matrix effect of NaCl mainly exists in the evaporation-atomization-excitation process of aerosol particles in ICP.
