Abstract: In this paper,the use of inductively coupled plasma atomic emission spectrometry（ICP-AES） Determination of feed at the same time Cu,Fe,Mn,Zn,Ca,Mg,P,Pb,Cr,Cd content of 10 kinds of trace elements.Analysis by selecting the appropriate conditions and sample handling methods,the linear range of up to three orders of magnitude,linear correlation coefficient greater than 0.999.Method of recovery is 85.0% ~ 96.5%,of each element relative standard deviation RSD were below 7 percent.Determination of national standards for the material results of corn meal more consistent with the standard values are within the margin of error.The method of determination of the actual sample results to national standards for comparison with measured results.The method is simple,rapid,high accuracy,precision,and apply to different trace elements in the determination of feed.
