| Abstract: | A method of simultaneous determining copper and iron elements in grape wine by Inductively Coupled Plasma Atomic Emission Spectrometry（ICP-AES） with microwave digestion was developed.Results show that the two elements have good linear correlation coefficient in grape wine.The standard curve has good linear relationship.The recovery rate is above 90%.The RSD is below 3.0%.The detection limit for Fe is 0.03 mg / L and Cu is 0.02 mg / L. |
