Quantifying P or PO4 in an unknown solid

  1. Dec 23, 2016 #1
    I have a solid sample possibly containing a few species of phosphate salts from a precipitation reaction. I am only concerned with the phosphorus in the solid sample. What are the possible methods of accurately measuring the P or PO4 content in the solid? Thank you!

    Yes I have also thought of this but I also thought maybe there are other possibly more accurate methods using some analytical instruments that can quantify the P or PO4 in a solid.

    Anyway, thank you for your insight. I really appreciate it!

    Standard approach in the analysis of steel was to dissolve the steel sample, oxidize P to PO43- and to determine it as the ammonium molybdophosphate (or with a colorimetric assay, as Ygg suggested).
