Who invented Purex?
Lionel S. Precourt
History. In 1922, Lionel S. Precourt and his son, Ray, began to make household bleach from their 400-square-foot (37 m2) garage behind the family home at 132 East 59th Place in Los Angeles, California. The following year, the name Purex was adopted for their bleach product.
What is the organic extractant used in the Purex process?
The organic solvent consists of 30% tributyl phosphate (TBP) in a hydrocarbon such as kerosene. Uranium ions are extracted as UO2(NO3)2·2TBP complexes; plutonium is extracted as similar complexes.
What is lanthanide extraction?
EXTRACTION OF LANTHANIDES Lanthanides can and actually have been extracted by each of the three main extrac- tion mechanism: formation of chelate complexes with acidic extractants, solvation of salts, and formation of ion pairs. Each of these systems has also been applied to their extraction chromatographic separation.
How are lanthanides extracted?
Complete step by step solution: These resins contain −SO3H/−COOH groups; the hydrogen in these resins is replaced with lanthanide ions. The aqueous solution contains a mixture of Ln+3, which is allowed to pass down a column with cation exchange resin.
