Rezumat:
p-tert-buthylthiacalix[4]arene, in which the four methylene bridges of p-tertbthylcalix[4]arene are replaced by sulfide linkages, is conveniently synthesized from mixture of p-tertbuthylphenol and elemental sulfur, tested in transport of metal cations through liqud membranes. Membrane system with p-t-buthylthiacali[4]arene as carrier was duble-jet liquid membrane. Pb(2+)cations were tested to verified abiliy of transport of p-t-buthyltiacalix[4]arene. Authors suggested a new scheme of cations transport through liquid membrane.
