摘　　要：目的：建立外科植入物用超高分子量聚乙烯中杂质元素钛（Ti）含量的检测方法。方法：采用微波消解和电感耦合等离子体质谱仪（ICP-MS）测定消解液中钛元素。结果：钛元素标准曲线的R^2值大于0.9996,回收率为94.4%-96.4%,10次重复测定结果的相对标准偏差（RSD%）为1.3%。结论：所建立的方法精密度高、准确性好、干扰较少、快速简单,可用于超高分子量聚乙烯中钛元素的含量测定。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 coefficient 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 accorate, little disturbance, rapid determination, simple operation, It can be used for determination of Ti elements in Ultra-high molecular weight polyethylene.
