Possibility of Modification of Zeolites by Iron Oxides and its Utilization for Removal of Pb(II) from Water Solutions [PDF]
Acta Montanistica Slovaca, 2004 Ion-exchange properties of cations from lattice and ions from solutions are characteristic for zeolites. Zeolites as sorbents are used in many branches of industry. Ion-exchange reactions of cations on zeolites have been a theme of many works.

Advanced Science, EarlyView.A PFSA/MXene composite membrane is developed for both PEMWE and VRFB applications. MXene incorporation simultaneously enhances proton conductivity and suppresses hydrogen/vanadium crossover. The interaction between MXene functional groups and PFSA's –SO3H reduces the proton diffusion barrier via hydrogen‐bonding networks, while the disordered ...

Enriched natural zeolites mineral fertilizer [PDF]
Acta Montanistica Slovaca, 2001 Clinoptilolit belongs to the big group of minerals called zeolites. Chemically they are alumosilicates and have a very difficult crystal structure. Nature zeolites are used as sorbents, molecular sieves and catalyzators.
