| Abstract: | A new UV-spectrophotometric method for determination of titanium in Ethylene glycol based on its complex reaction with H2O2 in sulfuric acid has been established.The maximum absorption wavelength of compound is at 410 nm.In this paper,the effects of various factors on UV-spectrophotometric determination of titanium have been studied.Some better results could be obtained when it is used to determine the amount of titanium in Ethylene glycol. |
