摘要: 利用X射线粉晶衍射法对金属板材及其磷化膜进行全谱和区段扫描,在确定镀膜中存在Zn2Fe(PO4)2·4H2O和Zn3(PO4)2·4H2O物相的基础上,求出Zn2Fe(PO4 2·4H2O的(100)和Zn3(PO4)2·4H2O的(020)衍射峰的计数强度,计算出样品磷化膜的磷比,从而判断出磷酸盐配比是否达到工艺要求.

Abstract: A method for the determination of high-content of copper in copper materials by flame atomic absorption spectrophotometry using sub-sensitive spectral line at 249.20 nm is reported in this paper. The effects of sub-sensitive spectral line, acidity of testing solution，co-existent metallic elements on the determination of Co were studied. The precision test was implemented for standard solution with Cu concentration of 400 μg/mL with precision of better than 0.82%RSD (n=11). The method has been applied to the determination of copper in copper concentrate, copper sponge and copper sludge, in which the copper content is less than 75%. The results are in good agreement with those by other methods.
