Daim ntawv thov ntawm nano Fe3O4 hais thiab lawv cov khoom hloov kho hauv kev tiv thaiv ib puag ncig feem ntau yog cov hlau nplaum adsorbent los ntxuav dej.Hauv cov txheej txheem ntawm kev kho dej, kev siv tshuab adsorption tau txais kev saib xyuas thoob plaws vim nws qhov zoo ntawm kev ua haujlwm yooj yim, tus nqi qis thiab kev ua haujlwm siab.Nto-hloov sib nqus nanoparticles muaj cov yam ntxwv ntawm thaj chaw loj tshwj xeeb, muaj peev xwm adsorption muaj zog, sib cais yooj yim, thiab rov ua dua tshiab, thiab muaj cov ntawv thov dav dav hauv ib puag ncig purification.
Nrog rau txoj kev loj hlob ntawm kev lag luam niaj hnub, qhov teeb meem ntawm cov hlau hnyav hnyav hauv dej ib puag ncig tau dhau los ua qhov hnyav dua.Cov pa phem hlau hnyav hauv dej feem ntau yog Pb2+, Hg2+, Cr6+, Cd2+, Cu2+, Co3+, Mn2+ thiab lwm yam.Hnyav hlau ions muaj qhov pom tseeb toxicity txawm nyob rau hauv tsawg heev concentrations, nkag mus rau hauv dej, av thiab cua, ua rau ib puag ncig muaj kuab paug;lawv tseem tuaj yeem nkag mus rau tib neeg lub cev los ntawm cov khoom noj khoom haus los ntawm bioconcentration, uas ua phem rau tib neeg kev noj qab haus huv.
Sib nqus sib cais tshuab los kho cov dej phwj tuaj muaj qhov zoo uas lwm cov thev naus laus zis tsis tuaj yeem sib xws, thiab nws tau ua lub luag haujlwm zoo hauv kev nqus cov hlau hnyav.

Saum toj no rau koj siv xwb, cov ncauj lus kom ntxaws daim ntawv thov yuav xav tau koj tus kheej kuaj, ua tsaug.
