Abstract:The determination of elements in Euonymus alatus by ICP-AES was carried out in the present paper. The Euonymus alatus samples were digested by microwave digestion technique. The optimized conditions of microwave digestion procedure obtained by orthogonal array design were as follows: the volume ratio of HNO3-HCl is 2∶1; the ratio of liquid/solid is 100∶1; the sample particle size is 100-140 mesh. ICP-AES method was applied to the determination of ten trace elements in the sample, and was compared with AAS. The results showed that the method was rapid and simple with the relative standard deviations between 0.5%-6.2%, and the recovery between 85.5% and 105.6%.
Key words:Microwave digestion;AAS;ICP-AES;Euonymus alatus; Trace elements
