Njira yotsatsa yamitundu iwiri ngati ntchito ya pH pamitundu itatu yotsatsira (goethite, Co-goethite, ndi magnetite) yawunikidwa.Makhalidwe a anionic adsorption adawonedwa pamitundu yonse pa goethite ndi Co-goethite.Mlingo wa adsorption unali wokhazikika mumitundu yosiyanasiyana ya pH yomwe idawerengedwa pomwe adsorbent inali magnetite.Mtundu wokhazikika wa capacitance (CCM) unagwiritsidwa ntchito kuti ugwirizane ndi zoyeserera.Mapangidwe apamwamba omwe aperekedwa kuchokera ku data ya adsorption anali ogwirizana ndi machitidwe omwe adapezedwa kuchokera ku FTIR spectroscopy ndi kuwerengera kwa ma molecular mechanics.Goethite ali ndi ntchito yabwino kwambiri monga adsorbent ya Alizarin ndi Eriochrome Blue Black R. Kukhalapo kwa cation yachilendo ku Co-goethite sikupititsa patsogolo luso la adsorption la goethite.Pa pH yotsika, kuchuluka kwa Alizarin ndi Eriochrome Blue Black R zotsatiridwa pa goethite ndi Co-goethite ndizofanana.Komabe, kudalira kwakukulu ndi kuwonjezeka kwa pH kumawonedwa ndi Eriochrome Blue Black R. Pa magnetite, kutsekemera kwa utoto kumasonyeza kugwirizana kochepa kwa mitundu yonse iwiri.Kulingalira kwamagetsi ndi steric kumatha kufotokozera zomwe zimapezeka mu kutengeka kwa mitundu iwiri pazitsulo zitatu zachitsulo zomwe zaphunziridwa mu ntchitoyi.
