Application

Iron is generally used as a catalyst for wide variety of organic transformations. It has been used for the synthesis of magnetic polydimethylsiloxane (PDMS) for automated microcontact printing of biomolecules.[1]
Iron can also be used:
  • For the removal of arsenate from water.[2]
  • To synthesize Fe(III) iodide catalyst for thioglycosylation of peracetylated saccharides.[3]
  • As a catalyst for the graphitization for microscale radiocarbon analysis of small samples.[4]
  • For the removal of nitroaromatic pesticides by reduction.[5]
