Abstract:
Contents of trace elements in sika bone powder were determined with microwave digestion and inductively coupled plasma mass spectrometry. Under the optimum conditions, the detection limits (3sigma, n = 11) are in the range of 0. 000 6-1. 498 ng x mL(-1) with relative standard deviations of 1.7%-6.8%. The recoveries are between 91% and 109%. The analytical results of national certified reference demonstrated the applicability of the proposed method.
