Hello all

I used to synthesis substituted hydroxyapatite using wet chemical process (Co-precipetation), but it leads me always to a structure full of Impurities, beside the uncomplet precepitation of the substituted metal seeing that the filtered solution still a little bit colored.

So could you please suggest a more efficient method to use or just give some advices about the wet chemical process.

thank you
