Method of manufacturing hydroxyapatite and aqueous solution of biocompounds at the same time

A method of manufacturing a hydroxyapatite and an aqueous solution of biocompounds from tissue by electrolyzing the tissue in an aqueous solution thereby dissolving and separating tissue components in the vicinity of anode, which comprises the steps of:

• (a) dissolving, in the vicinity of said anode, said tissue filled in an anode vessel of an electrolytic apparatus by passing an electric current through said tissue said electrolytic apparatus comprising;
• an electrolytic bath filled with an electrolyte;
• a cathode vertically disposed in said electrolyte;
• said anode vessel provided on an outer wall thereof with a large number of small holes for allowing said electrolyte to flow therethrough and entirely immersed in said electrolyte;
• and
• an anode vertically disposed in said anode vessel;
• (b) allowing part of said tissue components dissolved in the vicinity of said anode to crystallize in an aqueous cathode solution in the vicinity of said cathode;
• (c) filtering said electrolyte to obtain a filtrate and a residue;
• (d) obtaining said aqueous solution of biocompounds from said filtrate;
• and
• (e) obtaining said hydroxyapatite from said residue.
