Yuav ua li cas yog ion exchange resin activated
1. Cov txheej txheem tsim nyog rau kev ua kom tsis zoo thiab cation txauv resins polluted hauv kev kho cov chromium plating khib nyiab los ntawm ion txauv txoj kev.
2.Anion txauv resin tuaj yeem qhib rau hauv vitro. Tus nqi ntawm cov kua ua kom yog 1-2 npaug ntawm qhov ntim ntawm cov resin. Cov tshuaj ua kom tau npaj nrog sulfuric acid thiab sodium bisulfite ntawm qhov concentration ntawm 2.0-2.5MOL / L. Cov ntsiab lus ntawm sodium bisulfite yog 45G / L rau gel hom muaj zog alkali tsis zoo resin thiab 28G / L rau cov pore loj hom tsis muaj zog alkali tsis zoo. Thaum lub sij hawm ua kom tiav, cov resin tau tsau rau hauv qhov kev ua kom dej thaum hmo ntuj
3.Cation txauv resin, tuaj yeem qhib rau hauv lub cev. Tus nqi ntawm cov kua yog ob zaug ntawm qhov ntim ntawm resin. Cov tshuaj tua kab mob tau npaj nrog hydrochloric acid nrog rau qhov siab ntawm 3.0MOL / L, dhau los ntawm cov txheej txheem resin ntawm tus nqi ntws ntawm 1.2-4.0M / H, thiab tom qab ntawd tsau rau hauv sulfuric acid nrog lub ntim ntawm 1-2 npaug ntawm qhov ntim ntawm cov resin thiab qhov concentration ntawm 2.0-2.5MOL/L rau ntau tshaj 3H.
