| Abstract: | The content of titanium dioxide in wheat flour was determined by UV spectrophotometry and the experimental conditions were explored.The new analysis method of titanium dioxide in wheat flour was established,and the recovery of standard addition was from 90% to 102% with a fine precision.The method was simple and prone to the analysis of samples for large quantities.Precision and accuracy of the method could meet the requirement of the analysis. |
