本文提出了一种测定镉的亚稳态能量转移发射光谱法。利用低功率交流介电法获得活化氮。采用电热蒸发微量进样装置进样,在波长为326.1nm处,测得镉的检出限为0.2 ng/mL。
This paper presents a method for the determination of cadmium metastable energy transfer emission spectrometry. Activation of nitrogen using low-power AC dielectric method. The electrothermal evaporation microinjection device was used for injection. The detection limit of cadmium was 0.2 ng / mL at the wavelength of 326.1 nm.
