Iron Titration in passivation bath

Hi Everyone,

I am interested in finding a procedure for determining iron content in a passivation bath.
The make-up of the bath is 25% Nitric and 2-3% Sodium Dichromate.

Thank-you in advance

Hi -

Fe+3 can be done by titration pretty easily. Look for info on this site. Total iron can be done nicely with ICP.
