Hi researchers,
I want to make phase pure Lithium zeolite, and Li,K-Mixed zeolite?
I have tried substitution method on Zeolite Na-P1 with Li and K salts.
But no good substitution was observed. Only limited literature is available on Li-zeolites. If only substitution methods are available, how to get good substitution with Li and K ?
You could have a look at this article:
www.minsocam.org/ammin/AM49/AM49_656.pdf
where they explain their procedure for the ion echange of Na by various cations (including Li) in "Part Il-Structural and Compositional Effects of Cation Exchange". Slow percolation (2-5 days) of a solution of M+ (3-5 L of 5-20% solution of the salt for 5g of the zeolite)
Dear Murukutti.
Use Column Reactor instead of Batch Reactor to force the displacement of the chemical equilibrium.
If the crystalline phase of your material is stable try to make calcinations between successive ionic exchanges. This method was used in the 1970s, 1980s in some patents.
