Kev tu dej huv:
Tom qab cov resin tshiab tau ntim rau hauv kem, nws yuav tsum tau ntxuav los yog tsau nrog dej kub li qub (50-60 degree dej kub zoo dua) kom txog thaum cov dej ntshiab thiab tsis muaj xim lossis ua npuas dej.
B Dilute sodium hydroxide tov kev kho mob:
Concentration 6-8%, dosage 2-3BV, flow 1-1.5BV/HR; Ntxuav dej kom PH 9 lossis qis dua.
C Dilute hydrochloric acid kev kho mob:
Concentration 5-8%, dosage 2-3BV, flow 1-1.5BV/HR; Cov dej huv rau PH 5 lossis siab dua.
D resin ion daim ntawv conversion:
Raws li cov txheej txheem tsim khoom, xws li kev siv hom hydrogen ion, cov kauj ruam ua haujlwm tuaj yeem yog thawj B tom qab C, xws li kev siv sodium ion hom, tuaj yeem ua ntej C tom qab B ua haujlwm.
Feem ntau, cov resin tshiab raug kho 1-2 zaug raws li cov kauj ruam saum toj no thiab tuaj yeem muab tso rau hauv kev siv.
