Embodiment 1

[0026] Dissolve 0.5g of the compound Calix[4]Bis(18Crown6) shown in structural formula I in 45.0mL of dichloromethane, mix uniformly to obtain a solution; add 4.5gSiO to this solution 2 -P Stir evenly, and use a rotary evaporator to evaporate dichloromethane under reduced pressure to volatilize the methylene chloride until the material is in a near-dry state, and then vacuum-dry the near-dry material at 55°C for 24 hours to obtain an adsorbent.

Embodiment 2

[0028] Dissolve 0.5g of the compound Calix[4]Bis(18Crown6) shown in structural formula I in 40.0mL of dichloromethane, mix well to obtain a solution; add 4.0g of SiO to this solution 2 -P Stir evenly, and use a rotary evaporator to evaporate dichloromethane under reduced pressure to volatilize the material to a near-dry state, and then vacuum-dry the near-dry material at 50°C for 24 hours to obtain an adsorbent.

Embodiment 3

[0030] Dissolve 0.5g of the compound Calix[4]Bis(18Crown6) shown in structural formula I in 50.0mL of dichloromethane, mix uniformly to obtain a solution; add 5.5gSiO to this solution 2 -P Stir evenly, and use a rotary evaporator to evaporate dichloromethane under reduced pressure to volatilize the methylene chloride until the material is in a near-dry state, and then vacuum-dry the near-dry material at 60°C for 24 hours to obtain an adsorbent.

Abstract

The invention discloses a method for simultaneously separating rubidium and cesium from salt lake water. The method comprises the following step: mixing adsorbent and salt lake water, wherein rubidium and cesium in the ionic form in the salt lake water are subjected to adsorptive separation by the adsorbent; the adsorbent is prepared by loading a compound shown by structural formula I on a carrier; the salt lake water contains Rb(I), Cs(I) and other metal ions; the other metal ions include at least one of Li(I), Na(I), K(I), Sr(II), Mg(II), Ca(II) and Ba(II); and the pH value of the salt lake water is 9. The method for simultaneously separating rubidium and cesium from salt lake water can be used for realizing simultaneous adsorptive separation of rubidium and cesium from salt lake water, and is high in selectivity, simple to operate and high in separation efficiency.

Description

technical field [0001] The invention relates to the technical field of element separation, in particular to a method for simultaneously separating rubidium and cesium from salt lake water. Background technique [0002] Salt lakes are lakes with high salinity in arid areas, and the salinity is greater than 35g / L. Salt lakes are the product of lake development to old age. They are rich in various salts and are important mineral resources. [0003] Salt lake is a kind of saline water body, usually refers to lakes with salinity w(NaCleq)>3.5% (greater than the average salinity of seawater), and also includes dry salt lakes with dry surface brine and composed of saline deposits and intercrystalline brine (underground brine lake). There are about 200 kinds of salt minerals deposited in the salt lake. Human beings have mined a large amount of rock salt, alkali, Glauber's salt and potassium, lithium, magnesium, boron, bromine, saltpeter, gypsum and medical sludge from the salt l...
