Collaborative Study of the Determination of Iron and Aluminum in Baking Powder by Atomic Absorption Spectrophotometry
Keyword(s):
Abstract Commercial halting powder and samples containing added iron and aluminum were subjected to an interlaboratory study. The iron and aluminum were determined by an atomic absorption method reported earlier. The results for aluminum were satisfactory (average recoveries of 98, 99, and 107% for 3 levels) and the method has been adopted as official first action for aluminum. The iron results are somewhat erratic and study will be continued.
