摘　　要：通过微波消解-火焰原子吸收分光光度法对薯片中的铅含量进行了测定。结果表明:该方法准确度、精密度较高,方法检出限为0.19μg/mL,样品加标回收率为93%~106%。随后也对油炸薯片和烘培薯片中铅的测定结果进行了比较,发现油炸薯片中铅含量较高于烘培薯片中的铅含量,故建议人们不宜多食薯片,尤其是油炸薯片。The content of lead in potato crisp was determined by microwave digestion-flame atomic absorption spectrometry.The results showed that this method possessed high accuracy and precision,the detection limit was 0.19μg/mL,and the recovery of the method was ranged from 93%to 106%.Subsequently,the content of lead in fried and baked potato crisp was also compared,we found the content of lead in fried potato crisp was higher than that in baked potato crisp,therefore,it was suggested that people should not eat more potato chips,especially fried potato crisp.
