The bathophenanthroline spectrophotometric method was adapted for the determination of parts per billion iron in fuels. Particulate iron and soluble iron can be distinguished by analysis before and after filtering the fuel through a 0.45 micron methyl cellosolve, phenol-type antioxidants, and metal deactivator is demonstrated. Tenamene-2 interference is avoided by a procedural modification. Trace metals which normally are present in JP-6 fuels also do not interfere. Author
