Titanium anodes rau electrodeization (EDI): Tshuab cov ntsiab lus, xaiv cov hauv paus ntsiab lus thiab kev lag luam zoo

Electrodeization yog aHybrid Cais Txoj Kev Sib CavTus ntawd synergistically sib xyaw ion-sib pauv resins, ion-xaiv cov tshuaj txhuam kom ua tiav cov plua plav tsis tu ncua los ntawm peb txheej txheem ua ke ua ke:

Ion Kev tsiv teb tsaws nyob rau hauv DC teb: Thaum muaj peev xwm sib txawv (feem ntau 200-500 VDC) tau thov hla cathode, thaum Anode, LO₃⁻) Txav mus rau anode 26.

Xaiv membrane pom: Hloov suab-permeable thiab anion-permebranes tsim cov hmoov av zoo nkauj thaum lim dej kom ua rau cov dej ua kom huv si.

Electrochemical kev hloov dua tshiab: Cov dej sib cais ntawm cov hluav taws xob ua rau muaj kev sib txuas ua ke, tshem tawm cov tshuaj lom neeg ion-exchange xav tau kev txhim kho tshuaj lom neeg mus los ua si. Khov
