DEVELOPMENT OF THE METHOD OF OBTAINING TIOMOLIBDATE FROM MOLIBDATE OF AMMONIUM

Ammonium tiomolibdate has been obtained by passing hydrogen sulphide through a solution of ammonium molibdate in the presence of ammonium hydroxide. Factors influencing efficiency and purity of ammonium tiomolibdate have been examined. Tiomolibdate of ammonium with efficiency of 92,83% and purity of 97,23% has been obtained under optimal conditions. Appropriate ammonium tiomolibdates have been obtained through affecting ions of some metals on tiomolibdate.
