[Determination of inorganic elements in chicken muscle by sealed microwave digestion ICP-AES].
The contents of inorganic elements including K, Ca, Na, Mg, P, S, Fe, Cu, Mn, Zn, Mo, and Co from the chicken muscle were determined by ICP-AES using sealed microwave digestion. The sample of the chicken muscle was digested with HNO3-H2O2 system. The relative standard deviation was less than 5% for all the elements, and the recovery was 92.5%-110% by adding standard recovery experiment. This method was simple, sensitive and precise and can perform simultaneous multi-elements determination compared with conventional method of the chicken muscle determination, which could satisfy the sample examination request and provide scientific rationale for determining inorganic elements of chicken meat.
