Abstract

By using hydroxycalix[n]arene-p-sulfonates, H_j1_nⁿ⁻ (n = 6 and 8) known as super uranophiles, uranyl ion, UO₂²⁺, in aqueous solution was efficiently extracted by chloroform in the presence of methyltrioctylammonium chloride, MTA⁺Cl⁻. The extracted species were found to be the ionic associates, [(UO₂²⁺)(1₆⁸⁻)(H⁺)₋₃](MTA⁺)₉ and [(UO₂²⁺)₂(1₈¹²⁻)(H⁺)₋₃](MTA⁺)₁₁.
