四乙基铅是一种毒性大、挥发性较强的有机铅化合物，经过呼吸道、皮肤粘膜被人体吸收，造成急性或慢性中毒。目前多采用吸收管采样、萃取法处理样品、石墨炉原子吸收光谱法［１］测定空气中四乙基铅，但该法存在采样不便、样品处理繁琐等缺点。我们采取活性炭管采样，硝酸洗脱
Tetraethyl lead is a toxic, volatile organic lead compounds through the respiratory tract, skin and mucous membranes are absorbed by the body, causing acute or chronic poisoning. Absorption tube sampling and extraction are mostly used to treat samples. Graphite furnace atomic absorption spectrometry [1] is used to determine tetraethyl lead in the air. However, this method has some disadvantages, such as inconvenient sampling and complicated sample processing. We take activated carbon tube sampling, nitric acid elution
