基于X射线荧光光谱法的稻米镉含量的快速测定OACSTPCD
Quick determination of Cd in rice based on X - ray fluorescence spectrometry
采用X射线荧光光谱法对稻米中的镉含量进行测定，研究了测定时间、样品质量、样品粉碎粒度对测定结果的影响。结果表明，样品质量和样品的粉碎粒度对测定结果无显著影响，测定时间影响测定结果的稳定性。当测量时间达到720 s时，直接采用稻米样品进行测定，可准确获得稻米的镉含量，测定结果与AAS一致。
The content of Cd in rice was determined by X - ray fluorescence spectrometer. The influence of detection time,sample quality and granularity of sample on the detection results was studied. The re-sults showed that the detection results were not affected by the sample quality and granularity,while the stability of the detection results was affected by detection time. The content of Cd in rice sample can be detected accurately directly by XRF spectrometer wit…查看全部>>
