1. the extracting method of a pig protoheme, it is characterised in that, comprise the steps:

  • Step 1, the acid acetone adding 2 times of SOD production waste residue weight in SOD production waste residue, filter after stirring, collect filtrate;

    Step 2, in step 1 gained filtrate, add sodium acetate solution to filtrate for neutral, centrifugal rear collecting precipitation;

    The NaOH solution of step 3, the 0.05~

    0.15mol/L adding 4~

    6 times of precipitation volumes in step 2 gained precipitation makes resolution of precipitate, centrifugal rear collecting precipitation;

    Step 4, precipitate to step 3 gained in add hydrochloric acid to solution ph be 4.0, centrifugal rear collecting precipitation;

    Step 5, by dry for step 4 gained precipitation, obtain pig protoheme finished product.
