Abstract
By using hydroxycalix[n]arene-p-sulfonates, H(j)1(n)(n-)(n=6 and 8) known a s 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+)(1(6)(8-))(H+)(-3)](MTA(+))(9) and [(UO22+)(2)(1(8)(12-))(H+)(-3)] (MTA(+))(11).
