Inqubo yokukhangisa yodayi ababili njengomsebenzi we-pH kuma-adsorbents amathathu ahlukene (i-goethite, i-Co-goethite, ne-magnetite) ihlaziywe.Ukuziphatha okujwayelekile kwe-anionic adsorption kwabonwa kukho kokubili odayi ku-goethite ne-Co-goethite.Izinga le-adsorption lalihlala lingashintshile kububanzi be-pH efundwayo lapho i-adsorbent iyimagnetite.Imodeli ye-capacitance engaguquki (CCM) yasetshenziswa ukuze ilingane nemiphumela yokuhlolwa.Izakhiwo ezingaphezulu ezihlongozwayo kusukela kudatha ye-adsorption zazivumelana namaphethini atholwe ku-spectroscopy ye-FTIR kanye nesibalo se-molecular mechanics.I-Goethite inokusebenza okuhle kakhulu njenge-adsorbent ye-Alizarin kanye ne-Eriochrome Blue Black R. Ukuba khona kwe-cation yangaphandle ku-Co-goethite akuwathuthukisi amakhono okukhangisa e-goethite.Nge-pH ephansi, amanani e-Alizarin ne-Eriochrome Blue Black R adsorbed ku-goethite ne-Co-goethite afanayo.Kodwa-ke, ukuncika okuphezulu ngokunyuka kwe-pH kubonwa yi-Eriochrome Blue Black R. Ku-magnetite, i-adsorption yedayi ibonisa ukuhambisana okuncane kokubili odayi.Ukucatshangelwa kwe-elekthronikhi kanye ne-steric kungachaza izitayela ezitholakala ku-adsorption yamadayi amabili kuma-iron oxide amathathu afundwe kulo msebenzi.
