This invention provides a method for the synergistic separation of rubidium and cesium and the removal of silicon and aluminum from lithium slag. The method comprises the following steps: mixing lithium slag with an organic acid and performing a leaching reaction; after solid-liquid separation, obtaining a leachate and a leaching residue; applying an external field to the leachate to induce silicic acid condensation in the leachate to form silica gel; after solid-liquid separation, obtaining a desiliconized leachate and silica gel; mixing the desiliconized leachate with a complex-breaking agent and performing a complex-breaking treatment; then adding a precipitant to the solution after the complex-breaking treatment to precipitate aluminum ions; after solid-liquid separation, obtaining a rubidium-cesium leachate and an aluminum-containing precipitate; mixing the rubidium-cesium leachate with an extractant and performing rubidium-cesium extraction to separate a rubidium-cesium-rich organic phase and an aqueous phase. Furthermore, the method of this invention is simple, the reaction conditions are mild, it conforms to the concept of green chemical development, and it has good prospects for industrial application.

This invention discloses a method for manufacturing an ionic liquid-functionalized poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) thin film with adjustable work function, comprising: a pretreatment step, in which methanol is added to a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) solution to obtain a pretreatment liquid; a film forming step, in which the pretreatment solution is coated onto a substrate using a doctor blade to obtain a first-stage thin film; a film treatment step, in which DMSO is coated onto the first-stage thin film using a doctor blade and then the DMSO is washed away to obtain a second-stage thin film; and an ionic liquid treatment step, in which an aqueous solution of an ionic liquid is coated onto the second-stage thin film using a doctor blade and then the ionic solution is washed away to obtain an ionic liquid-functionalized poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) thin film, which not only has good mechanical stability, but also good conductivity and can achieve a changeable work function by using different ionic liquids.

The invention discloses a preparation method of salt-heat double-tolerant whey protein, which comprises the following steps: dispersing whey protein in water to obtain a solution A; the mass concentration of the protein in the solution A is 1-5%, and the pH is 7-9; performing ultrahigh pressure treatment on the solution A to obtain a solution B; the pressure of the ultrahigh pressure treatment is 300 to 600 MPa, and the time is 5 to 10 minutes; adjusting the pH value of the solution B to 4-5 to obtain a solution C; centrifuging the solution C, and recovering the precipitate; dispersing the precipitate in water, and adjusting the pH value to 6.0-7.0 to obtain a solution D; and drying the solution D to obtain the salt-heat double-tolerant whey protein. After being heated in a system containing NaCl or CaCl2, the salt-heat double-tolerant whey protein dispersion liquid (5%, w / w) still has good flowability. The salt-heat double-tolerant whey protein prepared by the invention can be used for preparing protein beverages or smokable gel rich in electrolyte.
