本文提出一种用浆样电热原子吸收光谱（ＥＴＡＡＳ）法测定荧光灯玻璃碎片汞含量的技术。具体做了以下几项工作：用硝酸钯作有效的基体改良剂；优化炉子程序；研究浆体的稳定性、汞在各种介质中的固液相之间的分布和钯改良剂的影响。采用最佳条件时，达到２４ｎｇｇ－１汞的检测极限（以３σ为基准）。对于磷样品中的１．５５和２．１６μｇｇ－１汞，ＲＳＤ（ｎ＝９）分别为８．３％和８．７％。用标准加入法进行校准，所得结果表明，此技术可有效且迅速地进行荧光灯玻璃碎片中汞含量的测定。
This paper presents a technique for the determination of mercury in fluorescent glass shards using the pulsed electrothermal atomic absorption spectroscopy (ETAAS). The following specific work has been done: using palladium nitrate as an effective matrix modifier; optimizing the furnace program; studying slurry stability, the distribution of mercury between solid and liquid phases in various media, and the effect of palladium modifiers. With the best conditions, the detection limit of 24 ngg-1 mercury (based on 3σ) is reached. RSD (n = 9) was 8.3% and 8.7%, respectively, for 1.55 and 2.16 μg-1 mercury in the phosphorus samples. The standard addition method is used for calibration. The results show that this technique can effectively and rapidly determine the mercury content of fluorescent glass shards.
