Abstract
A process for producing a titanium-molybdate material is provided. The process includes a step of reacting a metal molybdenum (Mo) material in a liquid medium with a first acid to provide a Mo composition and combining the Mo composition with a titanium source to provide a Ti—Mo composition. The Ti—Mo composition can be pH adjusted with a base to precipitate a plurality of Ti—Mo particulates.
Claims (13)
1. A titanium-molybdate (Ti—Mo) material, comprising:
a plurality of Ti—Mo particulates comprising a structure including a plurality of pores, channels, or both; and
one or more inorganic salts present in the structure, wherein an average size of the plurality of Ti—Mo particulates is in a range of from about 630 microns to about 1015 microns.
2. The titanium-molybdate (Ti—Mo) material of claim 1 , wherein the one or more inorganic salts comprise ammonium nitrate.
3. The titanium-molybdate (Ti—Mo) material of claim 1 , wherein the one or more inorganic salts are selected from the group consisting of ammonium chloride, ammonium nitrate, ammonium hydroxide, and a combination thereof.
4. The titanium-molybdate (Ti—Mo) material of claim 1 , wherein the Ti—Mo material comprises an eluting efficiency of 30% or greater.
5. The titanium-molybdate (Ti—Mo) material of claim 4 , wherein the Ti—Mo material comprises an eluting efficiency of 70% or greater.
6. The titanium-molybdate (Ti—Mo) material of claim 5 , wherein the Ti—Mo material comprises an eluting efficiency of 80% or greater.
7. The titanium-molybdate (Ti—Mo) material of claim 1 , wherein the Ti—Mo material is disposed in an elution column, and at least 90% of a total technetium content is released from the Ti—Mo material via passing an aqueous liquid through the Ti—Mo material.
8. The titanium-molybdate (Ti—Mo) material of claim 7 , wherein the aqueous liquid is selected from the group consisting of water, saline, dilute acid, and a combination thereof.
9. A cask transfer case comprising the titanium-molybdate (Ti—Mo) material of claim 1 .
10. A system for production of technetium comprising an elution column having a volume of at least 3 mL and the titanium-molybdate (Ti—Mo) material of claim 1 .
11. The system according to claim 10 , wherein the elution column has a volume of greater than 3 mL.
