Analysis of nitric acid in aluminum cleaning

I would like to know how to analyze nitric acid concentration in preliminary cleaning for anodizing aluminum metals. Thank you.

It isn't clear to me what process you are talking about, Eroina. A nitric-phosphoric bright dip maybe, or a nitric-acid based desmutter? Please tell us just a bit more about the solution you want to analyze. Thanks.
