  A mixed extractant solvent that includes at least one dialkyloxycalix[4]arenebenzocrown-6 compound, 4′,4′,(5′)-di-(t-butyldicyclohexano)-18-crown-6, at least one modifier, and, optionally, a diluent. The dialkyloxycalix[4]arenebenzocrown-6 compound is 1,3-alternate-25,27-di(octyloxy)calix[4] arenebenzocrown-6, 1,3-alternate-25,27-di(decyloxy)calix[4]arene-benzocrown-6, 1,3-alternate-25,27-di(dodecyloxy)calix[4]arenebenzocrown-6, 1,3-alternate-25,27-di(2-ethylhexyl-1-oxy)calix[4]arenebenzocrown-6, 1,3-alternate-25,27-di(3,7-dimethyloctyl-1-oxy)calix[4] arenebenzocrown-6, 1,3-alternate-25,27-di(4-butyloctyl-1-oxy)calix[4]arenebenzocrown-6, or combinations thereof. The modifier is a primary alcohol. A method of separating cesium and strontium from an aqueous feed is also disclosed, as are dialkyloxycalix[4]arenebenzocrown-6 compounds and an alcohol modifier.

  The present invention describes a method for purification of 225 Ac from irradiated 226 Ra-targets provided on a support, comprising a leaching treatment of the 226 Ra-targets for leaching essentially the entirety of 225 Ac and 226 Ra with nitric or hydrochloric acid, followed by a first extraction chromatography for separating 225 Ac from 226 Ra and other Ra-isotopes and a second extraction chromatography for separating 225 Ac from 210 Po and 210 Pb. The finally purified 225 Ac can be used to prepare compositions useful for pharmaceutical purposes.
• METHOD AND APPARATUS FOR EXTRACTION OF STRONTIUM FROM URINE

  The present invention provides an apparatus and rapid methods for extracting strontium ions from urine to provide a concentrated and purified strontium-90 extract suitable for scintillation measurements. The methods remove organic compounds, pigments, and alkali metal ions that can interfere with quantitative determination of strontium-90 in urine. A method of the invention comprises acidifying urine and removing organic pigments therefrom, loading a known quantity of so-treated urine onto a diphosphonic acid-based ion-exchange resin; flowing aqueous methanesulfonic acid through the diphosphonic acid-based ion-exchange resin to elute alkali metal ions therefrom; eluting strontium ions off of the diphosphonic acid-based resin and on to a strontium extraction chromatographic resin with a concentrated aqueous nitric acid solution; subsequently flowing water or a dilute acid stripping solution through the strontium extraction resin to strip the strontium from the strontium extraction resin; and collecting the strontium-containing stripping solution eluting from the strontium extraction resin.
