Cov txheej txheem adsorption ntawm ob dyes raws li kev ua haujlwm ntawm pH ntawm peb qhov sib txawv adsorbents (goethite, Co-goethite, thiab magnetite) tau txheeb xyuas.Kev coj tus cwj pwm anionic adsorption raug pom rau ob qho tib si dyes mus rau goethite thiab Co-goethite.Qib adsorption tau xyaum tas li nyob rau hauv qhov ntau ntawm pH kawm thaum lub adsorbent yog magnetite.Tus qauv capacitance tas li (CCM) tau ua haujlwm kom haum rau cov txiaj ntsig kev sim.Cov txheej txheem saum npoo tau thov los ntawm cov ntaub ntawv adsorption tau pom zoo nrog cov qauv tau los ntawm FTIR spectroscopy thiab kev suav cov tshuab molecular.Goethite muaj kev ua tau zoo heev li adsorbent ntawm Alizarin thiab Eriochrome Blue Black R. Lub xub ntiag ntawm txawv teb chaws cation hauv Co-goethite tsis txhim kho lub peev xwm adsorption ntawm goethite.Thaum qis pH, cov nyiaj ntawm Alizarin thiab Eriochrome Blue Black R adsorbed ntawm goethite thiab Co-goethite zoo sib xws.Txawm li cas los xij, kev vam khom ntau dua nrog kev nce ntawm pH yog pom los ntawm Eriochrome Blue Black R. Ntawm magnetite, cov xim adsorption qhia tsis tshua muaj affinity rau ob qho tib si dyes.Kev txiav txim siab hauv hluav taws xob thiab steric tuaj yeem piav qhia txog qhov tshwm sim hauv qhov adsorption ntawm ob dyes ntawm peb cov hlau oxides kawm hauv txoj haujlwm no.
