废脱硝催化剂钒、钨的浸出-搅拌对浸出率的影响

2019-9-2  The process of tungsten ion leaching was controlled by solid membrane diffusion. Under agitation condition(350 r/min), the apparent activation energy of tungsten leaching was 29.28 kJ/mol, while without agitation, the apparent activation energy was only 1.26 kJ/mol. Agitation could increase the diffusion rate, reduce the diffusion resistance, and enhance the leaching rates vanadium and tungsten.
