	abstract = {This work describes attempts to develop a new type of modified electrode with high selectivity for uranyl ions, UO22+. The goal was addressed by binding derivs. of calix[6]arene, a macrocyclic mol. composed of 6 phenol units known as a super uranophile, to the electrode surface. Selective extn. of UO22+ onto the electrode surface, followed by a voltammetric measurement provides a quant. uranyl anal. The initial approach to binding calix[6]arene mols. onto electrodes involved an ionic deriv., 4-sulfonic-calix[6]arene, electrostatically attached to a pos.-charged, self-assembled monolayer of cysteamine (2-aminoethanethiol) on a Au electrode. Attachment of the 4-sulfonic-calix[6]arene to the cysteamine monolayer was verified by XPS, IR spectroscopy, and capacitance measurements. Voltammetric expts. showed UO22+ can be pre-concd. and measured using these modified electrodes. [on SciFinder(R)]},
