| Abstract: | Aim To determine the kelp on human useful trace element content of the new method. Method The sample was dissolved by ashing method,Preparation of a series of standard solutions,The contents of 3 trace elements in kelp have been determined by air-acetylene fire atomic absorption spectrometry.Results the contents of Ca in the kelp are 1.77mg/g,Fe is 538 ug/g,Co is 22ug/g.recovery rate on marked is 97%-103%.the relation standard of deviation is lower 5%(Samples,n=7).Conclusion the result of the contents of 3 trace elements in kelp is accurate by air-acetylene fire atomic absorption spectrometry. |
