Objective: To develop a method for determination of Ti element in Ultra-high molecular weight polyethylene for surgery Implants. Methods: Ti element were determined by microwave digestion and inductively coupled plasma mass spectrometry(ICP-MS). Result:The interrelation coefifcient of calibration standards for Ti element was more than 0.9996, the recoveries of the addition standards for elements were between 94.4% and 96.4%.Conclusion: The results showed that this method was high precision and accurate, litle disturbance, rapid determination, simple operation, It can be used for determination of Ti elements in Ultra-high molecular weight polyethylene.
