Abstract
The purification of ammonium molybdates can be improved by ion exchange purifying ammonium molybdate solution.Experimental results indicate that JC-1 chelating resins can remove metal cations in ammonium molybdate solution.After purification,the content of divalent metals is less than 1 mg/kg in ammonium molybdate solution.Meantime,the quality of ammonium tetramolybdate can be improved.Compared with the common ammonium tetramolybdate,there is no change of crystal morphology of ammonium tetramolybdate from purified ammonium molybdate solution.
