Analysis of Trace Elements in Roughage by ICP-AES

Article Preview

Abstract:

In roughage, ten trace elements as Pb, Se, Mn, Se, Zn,Sb, Hg, Sn, Ca, Mg were detected by ICP-AES. Method of high pressure nitrifying pot is also selected to nitrify roughage. The relative standard deviation of measurement was less than 2.60%. The results accord with the demands of analysis trace elements. The experiment proved that roughage contained rich useful trace elements, which was green food with high nutrition.
