1, Txoj kev no siv tau rau kev ua kom cov anion thiab cation txauv resins thaum lawv kis kab mob thaum kho cov dej khib nyiab chromium plating siv ion txauv txoj kev.
2, Anion txauv resin tuaj yeem qhib rau hauv vitro. Tus nqi ntawm kev ua kom cov tshuaj yog 1-2 npaug ntawm qhov ntim ntawm cov resin. Cov tshuaj ua kom raug npaj nrog sulfuric acid thiab sodium bisulfite nrog ib qho concentration ntawm 2.0-2.5MOL / L. Cov ntsiab lus ntawm sodium bisulfite yog 45G / L rau gel hom muaj zog hauv paus anion resin thiab 28G / L rau macroporous qaug zog anion resin. Thaum lub sij hawm ua kom tiav, cov resin yog soaked nyob rau hauv lub activation tov ib hmos
3, Cation exchange resin tuaj yeem qhib tau hauv vivo. Tus nqi ntawm cov kua siv yog ob zaug ntawm qhov ntim ntawm cov resin. Cov tshuaj ua kom muaj zog yog npaj nrog hydrochloric acid nrog ib qho concentration ntawm 3.0MOL / L, dhau los ntawm txheej resin ntawm tus nqi ntws ntawm 1.2-4.0M / H, thiab tom qab ntawd tsau rau hauv sulfuric acid nrog ib lub ntim ntawm 1-2 zaug ntawm cov resin ntim thiab ib qho concentration ntawm 2.0-2.5MOL/L rau ntau tshaj 3 teev
Lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab qhov zoo thiab qhov tsis zoo ntawm ion txauv resin Cov khoom siv sib xyaw ua ke ionic ua haujlwm rau hauv cov khoom siv (organic polymer) hu ua "ion exchange resin" A resin nrog sulfonic acid ntawm nws qhov chaw hu ua cation txauv resin, thaum. ib tug resin nrog quaternary ammonium ions yog hu ua anion exchange resin. Vim nws lub peev xwm los tshem tawm cov anions thiab cations los ntawm dej, ion pauv resins feem ntau yog siv rau hauv kev tsim cov dej ntshiab thiab ultrapure. Txawm hais tias cov pab pawg ua haujlwm ntawm ion txauv resins tuaj yeem tshem tawm ions los ntawm cov dej nyoos, lub sijhawm dhau los, cov saturation ntawm cov pab pawg ua haujlwm ua rau txo qis deionization efficiency, ua rau cov dej tsis zoo. Tsis tas li ntawd, ion txauv resin nws tus kheej kuj yog cov khoom siv organic, uas tuaj yeem yaj thaum siv vim oxidation decomposition, mechanical rupture, thiab kev txhawb nqa tawm. Tsis tas li ntawd, cov khoom siv hluav taws xob them nyiaj kuj tuaj yeem raug adsorbed los ntawm ion pauv resins, ua rau lawv muaj kev cuam tshuam los ntawm cov organic teeb meem. Qee cov kab mob, vim yog qhov tsis zoo ntawm lawv lub cev, kuj yog adsorbed los ntawm cation txauv resins, ua rau cov resin nto ib qho chaw yug me nyuam rau cov kab mob thiab ua rau muaj kuab paug ntawm cov dej ntshiab. Nyob rau tib lub sijhawm, cov metabolites tsim los ntawm cov kab mob tuaj yeem dhau los ua qhov chaw ntawm cov teeb meem organic. Cov no yog txhua qhov chaw uas tsis tuaj yeem tsis quav ntsej thaum siv ion txauv resins, uas tuaj yeem ua rau dej tsis zoo. Ion txauv resins uas feem ntau poob lawv lub peev xwm tshem tawm ion (saturation) tuaj yeem rov tsim dua los ntawm kev ua ntawm cov kua qaub-puag cov neeg ua haujlwm kom ua tiav rov qab siv dua. Txawm li cas los xij, yog tias qhov ua tau zoo tsis zoo vim qhov adsorption (kev ua qias tuaj) ntawm cov khoom siv organic, qhov kev tshem tawm ntawm cov resin yuav txo qis. Tsis tas li ntawd, muaj kev pheej hmoo ntawm ion exchange resin paug nyob ntawm qhov zoo ntawm cov tshuaj siv rau kev tsim dua tshiab. Yog li ntawd, ion exchange resin siv nyob rau hauv ultrapure dej systems yuav luag tsis yooj yim sua kom rov tsim dua.
