General Description

Sodium bis(2-ethylhexyl) phosphate, also known as bis(2-ethylhexyl) sodium phosphate or NaDEHP, is an organophosphorus compound commonly used as a metal extraction agent in the mining and metal industry. It is a clear, colorless to yellowish liquid with a faint odor, and is soluble in water and organic solvents. Sodium bis(2-ethylhexyl) phosphate is known for its ability to extract metals such as uranium, rare earth elements, and transition metals from aqueous solutions. It is also used as a flame retardant in plastics, and as a plasticizer in the production of PVC. Due to its extraction and separation capabilities, sodium bis(2-ethylhexyl) phosphate is widely used in the production of various industrial products and in the processing of metals. However, it is important to handle this chemical with care, as it can be harmful if ingested or comes into contact with the skin or eyes.

Microstructure and magnetic properties of colloidal cobalt nano-clusters

The magnetic response of nanometer sized Co nanoparticles (NP) prepared using reverse micelle solutions are presented. The use of complementary structural and morphological probes (like transmission electron microscopy, high resolution electron microscopy, X-ray absorption spectroscopy) allowed to relate the magnetic properties to the size, morphology, composition and atomic structure of the nanoparticles. All data agree on the presence of a coreshell structure of NPs made of a metallic Co core surrounded by a thin Co-oxide layer. The coreshell microstructure of NPs affects its magnetic response mainly raising the anisotropy constant.

Homogeneous liquid-liquid extraction of metal ions with non-fluorinated bis(2-ethylhexyl)phosphate ionic liquids having a lower critical solution temperature in combination with water

Ionic liquids with an ether-functionalised cation and the bis(2-ethylhexyl)phosphate anion show thermomorphic behaviour in water, with a lower critical solution temperature. These ionic liquids are useful for homogeneous liquid-liquid extraction of first-row (3d) transition metals.
