SEPARATION OF TITANIUM, TUNGSTEN, MOLYBDENUM, AND NIOBIUM BY ANION EXCHANGE

The r es ul.ts of a ~ysten;atic study of t~e elution be~lavior of titanium, tungsten, moly b­ d enum, and 11l0blUm In vanous hydrochlonc-hydroflounc acid media are given. These data de~onstrate the behavior . of the anion c . omplex~s of thes~ el~ments on an anion-exchange r eSIn ~olumn. The posslbJI Jt y of severallllter es tJJl g quantItat Iv e separations is eviden t, and expenmen ts are descnbed t hat demons trate that t hese elem ents can be sepa rated from ea ch other.
