Sulfur-functionalized vegetable oils containing thioether groups have been shown to effectively remove Ag+ from aqueous solution. Interestingly, the absorption capacity differs depending upon the choice of which vegetable oil precursor is functionalized. In this study we will provide data for oils derived from corn and canola. The absorption capacity for both oils will be compared. A plausible explanation for why profound differences are observed will be proposed. The utility of this technology relates to both the ability to remediate heavy metals and recover precious metals using simple agriculture-based materials.
