Determination of trace titanium(Ⅳ) by inhibition kinetic spectrophotometry

LIU Lian wei (College of Science,Shandong Agricultural University,Taian 271018)  
A new inhibition kinetic spectrophotometric method for determination of trace titanium was proposed.Titanium(Ⅳ) can inhibit the discoloring reaction of H 2O 2 and neutral red catalyzed by Fe(Ⅲ) in dilute sulfuric acid and polyvinyl alcohol solution.The kinetic behaviour of this reaction was investigated. The linear range of the determination is 0.06~0.60 μg/mL with detection limit of 7 5×10 -2 μg/mL. This method was applied to the determination of trace titanium in human hair.
