摘要: Abstract Magnetic hybrid membranes based on ethylcellulose (EC), poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) and various magnetic praseodymium neodymium powder microparticles as fillers were obtained. Permeability, diffusion sorption coefficients of O 2 , N synthetic air components estimated for homogeneous heterogeneous using the Time Lag method constant pressure permeation technique. The microstructure studies phase analysis also performed SEM XRD. influence parameters, like coercivity, remanence saturation magnetization created gas transport properties was studied. results showed that their coercivity depended composition powder. On other hand, increased with increase addition in membrane. It found membrane's improved remanence, particle filling. decrease size associated positively influenced separation investigated membranes. observed had higher permeability, while permselectivity solubility coefficient values rather maintained or slightly increased. content enhanced significantly diffusivity EC PPO analyzed dependence drift w parameters correlation between membrane selectivity, permeability XRD characteristics stated.
