Predicting the Distribution Coefficient of Solvent Extraction of Rare Earth Elements Based on the Gibbs Free Energy and Thermodynamic Theory for Equilibrium Constant
… (REEs) are a class of 17 elements, including the lanthanides (15 elements), scandium (1 element), and yttrium (1 element). REEs minerals consist of 9-10 REEs excluding promethium. The separation of REEs minerals into their components is achieved by the solvent extraction process, consisting of …

Separation of Scandium and Calcium by Liquid-Liquid Extraction using Tri-N-Butyl Phosphate as Solvent
<p>Equilibrium data have been obtained for the systems Ca(N03)2- HNO3- TBP- H20 and Sc(N03)3- Ca(N03)2- HNO3- TBP- H20 over a wide range of concentration of the metal nitrates in the aqueous solution. Equilibrium acid concentration was used as a parameter for the equilibrium curves.</p><p>For the …

ADSORPTION OF ANTIBIOTICS BY VERMICULITE
<p>The occurrence of residual antibiotics in the environment has been a worldwide issue and warrants the development of inexpensive yet effective methods for antibiotics removal from contaminated water. In this thesis work, the adsorption of four antibiotics, namely chlorotetracycline (CTC), …

High Permeability/High Diffusivity Mixed Matrix Membranes For Gas Separations
The vast majority of commercial gas separation membrane systems are polymeric because of processing feasibility and cost. However, polymeric membranes designed for gas separations have been known to have a trade-off between permeability and selectivity as shown in Robeson's upper bound curves. The …
