熔融制样-X射线荧光光谱法测定产铀岩石中钨、钼、铌、钽、铁、磷、钒的标准方法
在铀矿石或者产铀岩石样品中,铌、钽、钼、钨、铁、磷、钒的含量往往较高。采用熔融制样-X射线荧光光谱法测定产铀岩石中高含量铌、钽、钼、钨、铁、磷、钒样品,通过人工配制工作标准,扩大了元素校准曲线的定量范围,采用理论α系数和经验系数法校正基体效应。采用此方法分析国家一级标准物质,各元素的测定值与标准值吻合;本方法的测量结果与ICP-MS法测量结果也基本一致。因此认为该方法可以用于产铀岩石中高含量铌、钽、钼、钨、铁、磷、钒的测定。此外该方法还可以满足硅酸盐样品、铀矿石、磷矿石等相似基体样品的测量要求。...

| Abstract_FL | The content of W,Mo,Nb,Ta,Fe,P,V are usually high in uranium ore or uranium-productive rock.The research focus on determing the high content samples of W,Mo,Nb,Ta,Fe,P,V by X-ray spectrofluorimetry method,through extending the calibration curve's quantitative range of these elements by artificial standard materials,the preparing method is fusion for Li2B4O7 and LiBO2-mixed flux,the correct method are theoretical α coefficients and the empirical coefficient.The validity of the method is substantiated by analyzing the national standard materials,the results are basically in accordance with reference contents.Additionally,the results which got by X-ray method are in accordance with the results of ICP-MS method.So this method is used to analyze high concentration of W,Mo,Nb,Ta,Fe,P,V about uranium-productive sample.This method also can analyze the silicate,uranium ore,and phosphate rock samples and other samples which are match the matrix of this method. |
