In this study the high extraction efficiency (a); low solubility in water (b), low toxicity (c), low cost (d), and high boiling point (e) are factors to consider during the selection of best organic solvents.Web

Turn off the Bunsen burner. Add about 2 cm 3 of dilute sulfuric acid to the solution, followed by hydrogen peroxide solution. A deep brown colour of iodine is formed as hydrogen peroxide oxidises the iodide ions present to iodine. Transfer the mixture to a separating funnel and add 10–20 cm 3 of cyclohexane.Web

The remaining iodine, which could not be precipitated due to its low concentration, was recovered by SX using xylene as an organic solvent diluted in kerosene.
