- •
Pervaporation of ammonia-solution using γ-alumina supported organosilica membranes was explored.
- •
Hybrid silica membrane exhibited ammonia selective transport at low ammonia concentration.
- •
Membrane degradation started to occur at high feed temperature and high ammonia concentration.
- •
Significant changes in crystalline γ-alumina structure undermined the functional silica separation layer.
