Leeching of Silver from Silver-Impregnated Food Storage Containers

Food storage containers may contain micro-particles of Ag, which serves as an anti-microbial agent to limit the growth of molds, fungi, and other microorganisms. Students study the leeching ability of three solvents — deionized water, tap water, and acetic acid — by measuring the concentration of silver in the leechate using graphite-furnace atomic absorption spectrophotometry. An analysis of variance is used to evaluate the relative importance of container type, solvent, extraction time, and the application of heat during the extraction.
