Solid Phase Extractant

A new solid phase extractant silica aerogel immobilized with Cyanex 301 {bis (2,4,4-trimethylpentyl) dithiophosphinic acid} (SAWC) was prepared via a sol-gel method and investigated for the extraction of Zn (II) from aqueous solution by a batch extraction technique. It is found that SAWC can extract about 100% zinc at equilibrium pH 1.7. Prepared SAWC was characterized by FT-IR, BET, EDX and SEM which proved the presence of Cyanex 301 into silica aerogel. Moreover, the material is also easily regenerated and reused in the subsequent removal of Zn (II) in five cycles. Therefore, it could be concluded that it may perform as a solid phase extractant in the extraction of metal ions from the aqueous solution.

Enthalpy Data

An electrostatic hydration model, that had previously been developed for ions of the noble–gas structure, was applied to the trivalent lanthanide and trivalent actinide ions. For the trivalent lanthanides it was found that a single primary hydration number resulted in a satisfactory fit of the model to the experimental free energy and enthalpy data. Subsequently, the model was applied to the trivalent actinide ions with a view to predicting values for the free energy and enthalpy of hydration for this series. A primary hydration number for the actinide series was determined by fitting the model to existing experimental enthalpy data for Pu3+. The predictions for this series were found to compare favorably with the few experimental and estimated values that exist.

A lanthanide series incorporating 2-thiophenecarboxylate and terpyridine is presented. Four structure types are observed with differences in the coordination number and nuclearity of the complexes attributed to the effects of the lanthanide contraction.
