Abstract:

A method combining on microwave sample digestion and inductively coupled plasma-mass spectrometry (ICP-MS) detection was established for determining of multiply inorganic elements in Bamboo leaves. Determination limits of 19 elements were in a range of 0.001～0.30 μg·g^-1, coefficients of variation (CV) were in a range of 2.19%～7.30%, and the recoveries of elements were in a range of 80.7%～122.4%. The results indicated that the method is simple, rapid, sensitive and accurate, and can meet the demand for 18 elements analysis in bamboo leaves. Ca, Mg, Fe, Al, Mn is relative abundant in the bamboo leaves.

Key words: bamboo leaves, elements, ICP-MS, microwave digestion
