| Abstract: | high purity titanium dioxide was digested by HF-HClO4-H2 SO4 and trace coloring impurity chromium was determined by ICP-AES. The influence of titanium matrix in the sample was eliminated by matrix matching method. The method is simple, reliable and accurate. The precision of the method is less than 5%. The recovery is 99.2%≤104.4%. The results are satisfactory. |
