Yi. Tarasevich et al., PREPARATION AND ADSORPTION PROPERTIES OF MICROPOROUS SORBENTS BASED ON MONTMORILLONITE AND BASIC SALTS OF ZIRCONIUM, Colloid journal of the Russian Academy of Sciences, 54(3), 1992, pp. 419-421
A sorbent with plastic micropores 0.54 nm thick and a specific surface
(with respect to argon) S = 210 m3/g is obtained on the basis of mont
morillonite and bask salts of zirconium. Adsorption and x-ray data are
used to determine the parameters of the primary and secondary pore st
ructures of the material and evaluate the content of packets with init
ial interlaminar cations Na+ in the final product.
