摘要
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。
The determination of cadimium with metastable energy transfer emission spectrometry isdescribed. The active nitrogen is produced in a low-power dielectric discharge generator. Thesample solution was introduced witn an electrothermal vaporization system, cadmium was de-termined at 326. 1 nm and the detection limit was 0. 2 ng/mL.
