Ammonium Metatungstate Production Method - Electrolysis

Introduction

Electrolysis is the production method to produce ammonium metatungstate, which is using electrode to precipitate the ammonia from ammonium paratungstate. Put the APT in anode chamber, after current passed, ammonia will be precipitate into cathode chamber through exchange film, then the solubility of AMT in cathode chamber is increased and the solution is produced. After crystallization, filtering and drying, the AMT powder is produced.
