Khoom Specification
Lanlang ® TA463D yog anion txauv resin nrog cov pab pawg tsis muaj zog [-N+(R2)·H2O] ntawm lub macroporous acrylic moj khaum. Feem ntau yog siv rau kev rho tawm, sib cais, thiab concentration ntawm uranium hauv alkaline leaching uranium mines.
Txoj kev alkaline leaching muaj ntau ntawm cov dawb humic acid thiab hydrosulfites hauv cov tshuaj leaching. Thaum siv styrene raws li muaj zog alkaline anion resins, cov impurity ions tsis tuaj yeem leached ua ke thaum lub sij hawm ib txwm leaching txheej txheem, thiab tsis tu ncua nyob rau hauv lub anion resin, yog li cuam tshuam rau adsorption ntawm uranium. Qhov tshwm sim no yog hu ua cov teeb meem organic pollution ntawm ion pauv resins.
Lub moj khaum tshwj xeeb acrylic thiab macroporous qauv ntawm Lanlang ® TA463D resin muaj siab uranium saturation adsorption muaj peev xwm, zoo heev tiv thaiv organic pollution, zoo hydrophobicity, anti osmotic siab zog, thiab ruaj khov physicochemical zog. Nws tuaj yeem zam cov pa phem ntawm anion resin thiab tswj nws qhov kev ua haujlwm ntev ntev rau uranium.
Uranium yog radionuclide, feem ntau tshwm sim hauv dej hauv av dua li cov dej saum npoo av, thiab feem ntau pom ua ke nrog radium. Kev txo qis ntawm cov dej teeb meem yuav xav tau kev kho mob kom tshem tawm ob qho tib si uranium thiab radium.Uranium feem ntau muaj nyob hauv dej raws li uranyl ion, UO22+, tsim nyob rau hauv muaj oxygen. Ntawm pH saum toj no rau, uranium muaj nyob hauv cov dej haus uas feem ntau yog uranyl carbonate complex. Daim ntawv no ntawm uranium muaj kev sib raug zoo heev rau lub hauv paus muaj zog anion resins.
Tus txheeb ze kev txiav txim ntawm affinity ntawm lub hauv paus muaj zog anion resins rau qee yam ions hauv dej haus qhia uranium nyob rau sab saum toj ntawm daim ntawv:
Uranium/Perchlorate >>Sulfate / Chromium> Selenium / Arsenate> Nitrate> Chloride> Bicarbonate> Fluoride.
Resin xaiv
Cation resin nyob rau hauv daim ntawv hydrogen tau pom kom tshem tawm uranium, tej zaum los ntawm kev hloov cov uranium complex mus rau uranium cation. Kev tshem tawm cov nqi yog nyob rau hauv 90-95% ntau, tab sis cov pH ntawm cov effluent yuav qis (kwv yees 2.5 mus rau 3.5) thiab cov resin siv nyob rau hauv txoj kev no tsis xaiv, tshem tawm tag nrho cov cations.
Cation resin nyob rau hauv daim ntawv sodium, ua hauj lwm raws li ib tug softener, muaj kev txwv siv nyob rau hauv uranium tshem tawm thiab yog heev pH nyob ntawm seb. Ntawm pH 8.2, tsis muaj uranium tshem tawm, thiab ntawm pH 5.6 muaj li 70% tshem tawm. Raws li cov resin tso rau hauv daim ntawv calcium, kev tshem tawm txawm tias tsis zoo, tsis muaj kev tshem tawm ntawm pH 8.2 lossis 7, qee qhov kev tshem tawm pib tshwm sim ntawm pH 5.6, thiab 60% tshem tawm ntawm pH 4.
Daim ntawv pov thawj
Lanlang yog tus tswv cuab ntawm American Water Quality Association. Hauv xyoo 2016, Lanlang tau txais WQA Certification nrog NSF / ANSI61 thiab 372 tus qauv. Thiab hauv 2022, Lanlang tau txais NSF Certification nrog NSF / ANSI44 thiab 42 tus qauv.
