Analysis of Titanium Alloy by Inductively Coupled Plasma Atomic Emission Spectrometry

An ICP-AES method for determination of aluminum,chromium,iron,molybdenum and zirconium content in titanium alloys was established.Titanium alloy was dissolved with hydrochloric acid. The sample solution was detected by inductively coupled plasma atomic emission spectrometry with an internal standard for overcoming matrix interferences.The detect limits for aluminum,chromium,iron, molybdenum and zirconium were 0.040 mg/g,0.004 mg/g,0.005 mg/g,0.002 mg/g and 0.002 mg/g, respectively.Relative standard deviations of the test results were in the range of 0.47%～1.42%(n=6).
