摘要
铅作为一种对人体有害元素,检测大米样品、尤其是产自水或土壤受到污染地区大米样品中的铅是非常必要的。应用氢化物原子荧光光谱法检测铅的含量,具有取样量少、灵敏度高,检出限低等优点。该方法的线性范围为0-100μg/L,相对标准偏差(RSD,n=6)2.7%-5.9%,检出限为0.52μg/L,加标回收率为85%-110%。
Lead is a dangerous matter to people,It is necessary to detect lead in rice,especially in the area polluted.De-termination of lead in mice by atomic fluorescence spectrometry with microwave digestion has following advantages: less dosage of samples,high sensitivity,low detection limit,and so on.The linear range for this method is 0 ~ 100μg/L,the precision is 2.7%-5.9%(RSD,n=6),the detection limit is 0.52μg/L,and the recovery is 85.0%-110%.
