摘　　要：采用尘毒多功能采样仪在某车间内采集铅烟样品,用硝酸-高氯酸完全消解后,用火焰原子吸收光谱法测定铅烟中铅的含量,从而得出车间空气中铅烟含量。采用此方法的线性良好,具有良好的准确度和精密度,符合测定要求,能够准确快速的测定车间空气中铅烟含量。The lead smoke samples were collected in a workshop with a multifunctional dust sampling instrument,after being completely digested by nitric acid-perchloric acid,the lead content in the lead smoke was determined by flame atomic absorption spectrometry,thus the lead smoke content in the air of the workshop was obtained.This method has good linearity,good accuracy and precision,and can be used to accurately and rapidly determine the content of lead smoke in the air of workplace.
