Aluminum is a biologically nonessential metal that humans are often exposed to and consume in their average daily diet. It is found in commercial cake mix in the form of sodium aluminum phosphate, a leavening agent. This study reports on the analysis of several commercial cake mixes for aluminum using flame atomic absorption spectroscopy (FAAS). The commercial cake mix samples were dry ashed in a silica crucible in a muffle furnace at high temperature and subsequently dissolved with nitric acid. To minimize the matrix effect on the analytical signal, the multiple-increment standard addition method was used in sample preparation prior to the analysis step. Atomization was accomplished with a nitrous oxide/acetylene flame, and absorbance measurements were made at the 309.27 nm aluminum resonance line. The study included assessing the effect of adding ionization suppressor to the samples.
