| 摘 要： | 采用石墨炉原子吸收光谱法测定农产品中痕量铍，比较了微波消解和电热板消解两种前处理方法，选择了基体改良剂。方法在0μg／L—4.00μg／L范围内线性良好，微波消解法和电热板消解法的检出限分别为0.002mg／kg和0.0002mg／kg，标样平行测定的RSD为2.4％—4.1％，农产品加标回收率为80.0％—95.0％。

| Abstract: | Thetrace Beryllium in agriculturalproductswasdetermined bygraphitefurnace atomic absorptionspectrometry. Thetwotreatmentmethodswere compared between microwave digestion and electric heating board digestion. A matriximproverwaschosen. A good linearity wasinrangefrom 0g/L to 4.00g/L. The detectionlimitsofmicrowavedigestion and electro thermalboard digestionwere0.002mg/kgand 0.000 2mg/kgrespectively. Parallelstandard samplestestresultsofRSD wereinrangefrom 2.4% to4.1%. Spikerecoveryof agriculturalproductssamplesranged from 80.0% to95.0%. |
