| 中文摘要: |
| 采用微波消解-氢化物发生原子荧光光谱法同时测定芦苇中砷和镉, 优化了试验条件。砷在0μ g/L ~ 80.0μg/L 、 镉在 0μg/L~ 10.0μg/L 范围内线性良好, 检出限分别为 0.010μg/L 和 0.012μg/L, 样品测定的RSD为 0.7%~ 2.0%, 平均加标回收率为 84.0% ~ 107% 。 |

| Themethod ofmicrowave digested-hydridegeneration atomic fluorescencespectrometry wasestablished fordetermination ofthearsenicandthecadmium in reed. Thetestconditionswereoptimizedtoobtain following results: good linearity ofthe arsenic from 0μ g/L to 80.0μg/L, ofthe cadmium from 0μg/L to10.0μg/L; the detection limitsofarsenic at0.010μg/L, ofcadm ium at0.012μg/L; the RSD ofsamples from 0.7% to 2.0% ; the averagerecoveriesfrom 84.0% to107%. |
