Abstract
The selective uptake of strontium by a specially tailored aluminum pillared montmorillonite was investigated. Selective exchange kinetics revealed a f ast component of the order of less than one hour, while exchange isotherms revealed the preference for strontium uptake over sodium and calcium with s eparation factors alpha(Na)(Sr) = 50 and alpha(Ca)(Sr) = 2. In an environme nt of rumen liquid taken from slaughtered sheep. 26% of strontium was remov ed by 1 g and 40% by 3 g of material.
