DETECTING FREE IRON

DETECTING FREE IRON 
 
Free iron cannot be seen on the surfaces of contaminated parts. Therefore, it must be converted into a visible form.   
Ferroxyl Test Kit helps to Identify transition Iron metal ions to blue colour spot.

The transition of Iron metals to form blue coloured compounds with TK F1 and TK F2.

colourless solution → blue precipitate  

Use the ferroxyl test  TK F1 and TK F2  Spray the surface with a solution of potassium ferricyanide. If free iron is present, a blue color will appear. This test is extremely sensitive and often gives false positive results, that is, it gives an indication of iron being present when it really is not. The ferroxyl solution must be made fresh each day. The ferroxyl tests are described in ASTM A380.
