摘要：

A study was made on the determination of elemental composition of the bread improver using energy-dispersive X-ray fluorescence. Enrichment of I and Ca was seen in the bread improver. Concentration of I with an annular Am-241 radioactive source and concentration of Ca with an annular Fe-55 radioactive source were determined by using standard addition method in 2pi geometry. A Si(Li) detector and a multichannel analyzer were used to measure I and Ca concentrations in the bread improver. (C) 2002 Elsevier Science Ltd. All rights reserved.
