Any suggestions on getting iodine into a peanut oil solution?
Sure would appreciate some help.

Peanut oil contains mostly mono- and di-cis-unsaturated straight-chain fatty acid triglycerides, mostly C-16 and C-18, particularly of oleic (60%),
linoleic (20%), linolenic, arachic, arachidic, and arachidonic acids, along with 12% of unsaturated acids (stearic and palmitic). The iodine would add
across the double C=C bonds, especially if exposed to natural light. In fact, the "iodine number" of vegetable oils is a method of measuring and
quoting their degree of unsaturation.

I believe that they are asking how to deliver iodine for an iodine number determination. More information about what you're trying to do would be
helpful. I believe chloroform, carbon tetrachloride, or either hexane or heptane are probably the best delivery options.

There should be something on "iodine number" determination of the unsaturation of unsaturated fatty acid triglycerides in vegetable oils in this
reference which I have uploaded:
