| Abstract: | In this paper, orthogonal test was applied to determination of trace elements in wild vegetables just as Mn, Se, Cu, Fe, Mg and Zn by ICP-AES. It could provide many informations for us by less experimental times, and could choice the best experimental (conditions) by square-error analysis. It would be helpful for improving experimental accuracy. The method was simple, rapid, and (possessed) of highly sensitivity, good accuracy and determination of many elements at the same time, in addition little environment pollution. The recoveries of the method were in the range of 97.2%-103.3%, and relative standard deviations were less than 2.15%. The experimental (results) proved wild vegetables were valuable and nutritious food, they had rich trace elements. |
