The disadvantage of the traditional ammonium tetramolybdate (ATM) production process is a large consumption of nitric acid. Therefore a novel process for the generation of ammonium isopolymolybdate solution from ammonium molybdate solution using bipolar membrane electrodialysis (BMED) was developed and the batch experiment was carried out in this paper. The BMED process was studied to optimize various parameters such as initial base solution, final electrolytic pH value of salt solution, current density, initial NH₄HCO₃ concentration of base solution and Mo concentration in feed solution. The average current efficiency was 82%, the power consumption was 0.058 kWh/mol NH₄⁺ or 0.887 kWh/mol Mo, and the recovery rate of Mo reached 99.4% under the optimal conditions of a current density of 500 A/m², an initial Mo concentration of 173 g/L in the salt compartment, an initial NH₄HCO₃ concentration 2.0 mol/L in the base compartment, an initial (NH₄)₂CO₃ concentration of 1.0 mol/L in the electrode solution and 32 ± 0.5 °C and a final solution pH of 4.0 in the salt compartment.

传统的四钼酸铵（ATM）生产工艺的缺点是硝酸消耗量大。因此，开发了一种利用双极膜电渗析法从钼酸铵溶液中生成异聚钼酸铵溶液的新方法，并进行了批量试验。研究了BMED工艺以优化各种参数，例如初始碱溶液，盐溶液的最终电解pH值，电流密度，初始NH ₄ HCO ₃碱溶液浓度和进料溶液中Mo浓度。平均电流效率为82％，功耗为0.058 kWh / mol NH ₄ ⁺或在0.887 kWh / mol Mo的条件下，在电流密度为500 A / m ²，盐室中的初始Mo浓度为173 g / L，初始NH ₄ HCO的最佳条件下，Mo的回收率达到99.4％₃在基础隔室中的浓度为2.0 mol / L，在电极溶液中初始（NH ₄）₂ CO _3的浓度为1.0 mol / L，在盐室中的初始浓度为32±0.5°C，最终溶液的pH为4.0。
