| 摘 要： | 感光级硝酸银样品经一系列的化学处理后,上清液采用石墨炉原子吸收分光光度法测定其中Bi,Cd,Cr,Cu,Fe,Mn,Ni,Pb,Sb,Sn,Te,Se,Zn元素的含量,本方法测定Bi,Cd,Cr,Cu,Fe,Mn,Ni,Pb,Sb,Sn,Te,Se,Zn各元素均能得到良好的标准曲线,即r=0.99~1;Cu、Cr、Ni、Sb、Sn、Mn、Te、Se的回收率较好,一般可达到95%~110%,Zn、Bi、Cd、Pb的回收率较低,经常只有50%~60%。

| Abstract: | We treated photosensitive silver nitrate with series of chemical treatments, and tested Bi, CA, Cr, Cu, Fe, Mn, Ni, Pb, Sb, Sn, Te, Se, Zn in the superstratum with graphite furnace atomic absorption spectrophotometer. By this method, these elements can get nice standard calibration and the calibration curve was between 0.99 to 1. Recycle rate of Cu, Cr, Ni, Sb, Sn, Mn, Te, Se test was between 95 % to 110 % and that of Zn,Bi,CA,Pb test was always between 50 %- 60 % . |
