【Abstract】 A new method was proposed to preconcentrate of trace elements by solid phase extraction with microcrystalline naphthalene.Trace elements 8 Hydroxyquinoline complex were absorbed onto microcrystalline naphthalene quantitatively under certain conditions the effects of various experimental parameters were optimized. The method was applied to the analysis of standard reference materials. All elements are in good agreement with reference value.更多还原
