▎ 摘 要
NOVELTY - The preparation process of ammonium paratungstate involves weighing tungsten trioxide as anode electrode and graphene-modified carbon rod as cathode electrode and then catalyzing to obtain sodium tungstate, introducing ammonia gas into sodium tungstate, maintaining temperature at 3-10 degrees C and then filtering, separating to obtain crude ammonium paratungstate and then decomposing, washing using ammonium salt solution and deionized water, analyzing using resolving agent and then recrystallizing at 82-85 degrees C and decomposing. USE - The process is useful for preparation of ammonium paratungstate. ADVANTAGE - The process enables economical preparation of ammonium paratungstate with high purity.
