Screening Analysis of Trace Heavy Elements in Powdered Milk by EDXRF

One of the methods used for testing for heavy metals in foods is the color reaction method, but since this method does not provide for attribution of metals (elements) or is influenced by sample components, elemental analysis such as AA is used. But due to the laborious sample preparations, such as component extraction and acid decomposition, etc., that are required, in addition to subjective variation in colorimetric determination, these methods have become a problem in the manufacturing process and in quality control. Therefore, we investigated the use of the EDX method, which enables convenient analysis from sample pretreatment to measurement and finally to determination in the examination of powdered milk.
