Induced Adsorption

The synergistic adsorptive accumulation of metal ions at the surface of mercury electrodes is described. The basic thermodynamic relationships between the ionic species involved in the synergistic adsorption are developed and analysed. The method is compared with the simple anion-induced adsorption. The synergistic adsorption of uranyl ions in the system salicylic acid-tributylphosphate is reported.

Assembled Monolayers

The development of a microcantilever (MCL) sensing device capable of simultaneously detecting several metal ionic species in aqueous media with low limits of detection requires a variety of sensing layers which are ion-specific. Calix[4]arenes are robust molecules which can be easily modified and have been extensively studied for their ion binding properties. They are also capable of forming self-assembled monolayers (SAMs) onto the gold layers of MCLs and are capable of detecting various metal ions with different anionic counterions in aqueous solutions. In this paper we report on the effect of the alkoxy group in the narrow rim [O-(alkoxycarbonyl)methoxy] substituents of bimodal calix[4]arenes which have been used as metal ion MCL sensing layers, using classical solution state experimental studies. A DFT computational study to compare the experimental results with several metal ions is also reported herein.

A simple and reliable colorimetric probe N,N'-Bis-(4-diethylamino-2-hydroxybenzylidene)-1,10-phenanthroline-2,9-carbohydrazide (L) has been synthesised by reacting 4-(diethylamino) salicylaldehyde with 1,10-phenanthroline-2,9-dicarbohydrazide. Sensing ability of L was studied by interacting with various f-block metal ions...
