| Abstract: | Titanium ions(TiO2+) can react with hydrogen peroxide(H2O2) to produce the yellow complex Ti(H2O2) 2+],so the spectrophotometer method can be used to determine titanium content.When titanium content is in the range of 0～35 μg,linear relationship is well and complies with Lambert-beer law.Titanium content in CS series high efficiency catalyst for propylene polymerization usually is 2.00%～6.00%,the analysis method is suitable,it has high detection speed,high accuracy and precision. |
