摘 要: | 利用元素分析建立四个产地香米的鉴别方法。利用电感耦合等离子体质谱法和电感耦合等离子体光谱法对来自泰国、越南、柬埔寨、巴基斯坦四个地区的220份香米进行包括钙、铁、钾、镁、锌、硼、铝、铬、锰、钴、镍、铜、砷、锶、硒、镉、铯、钡、铅19种元素在内的含量分析。通过判别分析建立判别模型。判别模型自校验交叉校验准确率100%,拥有极高的准确率。

Regional Discrimination of 4 Kinds of Imported Rice by Multi-element Analysis |
| |
Abstract: | The research set up a regional discrimination method for 4 imported rice by combination multi-element analysis. 220 different rice from origin place were collected, including Thailand, Vietnam, Cambodia, Pakistan. The concentration of 19 elements(Ca, Fe, K, Mg, Zn, B, Al, Cr, Mn, Co, Ni, Cu, As, Sr, Se, Cd, Cs, Ba, Pb) were determined by ICP-MS or ICP-OES. Discriminatory analysis was applied in building up a regional discrimination model, which both self verification and cross validation accuracy were as high as 100%. |

Keywords: | rice inductively coupled plasma-atomic spectrometry(ICP-MS) inductively coupled plasma-atomic emission spectrometry(ICP-OES) regional discrimination |
