微波诱导等离子体原子发射光谱法测定汞的研究

Determination of Mercury by Microwave Induced Plasma Atomic Emission Spectrometry

摘要: 研究了以常压低功率氩微波诱导等离子体为激发源的原子发射光谱测定Hg的方法。采用超声雾化、水冷凝、浓H_2SO_4吸收去溶的进样方法,考察了微波前向功率、载气流速、KCl和NH_4Cl浓度、酸度等因素对Hg发射强度的影响。方法已用于试样分析。

Abstract: A low-power argon microwave induced plasma was used as an excitation source, with an ultrasonic nebulization system for sample introduction. A heated tube, a condenser and a concentrated H2SO4 desiccator were used for desolvation. Experimental parameters
