A simple test for peroxides in water-immiscible solvents

Shake 2 ml of solvent with 1 ml of a freshly prepared KI solution (10% in water) and a drop of starch indicator solution, a blue color is rapidly developing if peroxides are present (a faint yellow/brown color after addition of KI indicates low levels of peroxides).
