  • Publication number: 20240183002
    Abstract: A method for lithium adsorption in a carbonate- and/or sulfate-containing solution, comprising using an aluminum-based lithium adsorbent for adsorption of lithium ions in the carbonate- and/or sulfate-containing solution, after the adsorption is saturated, using a weakly acidic high-concentration salt solution to transform the adsorbent, desorbing the transformed adsorbent by means of a low-concentration salt solution or water, and entering the next cycle for operation.

  • Patent number: 11918971
    Abstract: Disclosed in the present disclosure are a lithium adsorbent and a preparation method therefor. The lithium adsorbent has a porous structure, and includes an aluminum-based lithium adsorbent active material and a hydrophilic binder; and the lithium adsorbent has an average pore diameter ranging from 1 nm to 10 nm, a pore volume ranging from 0.65 ml/g to 0.8 ml/g, and a specific surface area ranging from 400 m2/g to 600 m2/g. The lithium adsorbent of the present disclosure has a specific average pore size ranging from 1 nm to 10 nm, lithium ions have a diameter of 0.3 nm, and the pore size of the lithium adsorbent of the present disclosure is three times or more greater than the diameter of the ions so that the lithium ions can quickly enter and exit pores.

  • Patent number: 6993600
    Abstract: A controller for a writable optical media is presented. The controller includes a write control sequencer that monitors the transmission of data from a host device to the writable optical media without continuous supervision from a microcomputer. The write control sequencer monitors and controls data flow in response to descriptors which are loaded into the controller prior to the transfer by a microprocessor.
