The brief overview of the pretreatment method of tea and analytical method of rare earth elements are introduced,including ashing method,wet digestion method and microwave digestion method;spectrophotometry,inductively coupled plasma optical emission spectrometry (ICP-OES ), inductively coupled plasma mass spectrometry (ICP-MS ) and neutron activation analysis (NAA ). Comparatively,the method based on microwave digestion and ICP-MS,which is precise and simple for determining rare earths in different type tea,is the main analysis method recommended.
