General Description

Holmium is a chemical element with the symbol Ho and atomic number 67. It is a silvery-white, rare-earth metal that is relatively soft and malleable. Holmium is found in the Earth's crust, but only in small quantities, and is primarily obtained from the minerals monazite and gadolinite. It is used in various industrial and research applications, including as a component in some types of electronic devices and as a dopant in solid-state lasers. Holmium also has medical applications, as it can be used in nuclear reactors to create radioactive isotopes for cancer treatment. Overall, holmium is a versatile and important element with a range of practical uses in various fields.

Liquid-liquid solvent extraction of rare earths from chloride medium with sec-nonylphenoxy acetic acid and its mixtures with neutral organophosphorus extractants

In the present study, sec-nonylphenoxy acetic acid (CA100) and its mixtures with four neutral organophosphorus extractants, tri-butyl-phosphate (TBP), 2-ethylhexyl phosphonic acid di-2-ethyl ester (DEHEHP), Cyanex923, and Cyanex925 have been applied to the extraction of rare earths. Results show that all the four mixing systems do not have evident synergistic effects on the extraction of rare earths. The different extraction effects have been considered to the separation of rare earths. The four mixtures may be applied to the separation of yttrium from some certain lanthanoids at proper mole fractions of CA100. Pleiades Publishing, Ltd., 2011.

Effect of the 18-crown-6 and benzo-18-crown-6 on the solvent extraction and separation of lanthanide(III) ions with 8-hydroxyquinoline
