Iodine value in Bio Diesel (BDF)

The iodine value is expressed in grams of iodine for the amount of halogens linked with 100g test sample, and is used as degree of unsaturated bond of fats and oils or Bio Diesel Fuel.
The test method to determine iodine value in Bio Diesel Fuel is standardized as in ASTM D1959-97 Standard Test Method for Iodine of Drying Oils and Fetty Acids, ISO 3961:1996 to determine iodine value in animal and vegetable fats and oils and JIS K0070-1992 Test Method for Acid value, Saponification number, Ester number, Iodine number, Hydroxyl value of Chemical products.
The test sample is made out of bio diesel fuel dissolved in cyclohexane, added in excess with Wijs reagent (0.1mol/L iodine monochloride acetic acid solution), left in dark room for 30 minutes reaction, then added with potassium iodide, potentiometric titrated with 0.1mol/L sodium thiosulfate solution for the excessive iodine monochloride to the endpoint, which is the highest inflexion point.
The iodine value of BDF is calculated from titration volume of sodium thiosulfate solution.
