Ua nānā ʻia ke kaʻina hana adsorption o ʻelua mau kala ma ke ʻano he pH ma luna o ʻekolu adsorbents like ʻole (goethite, Co-goethite, a me magnetite).Ua ʻike ʻia ka hana hoʻoheheʻe anionic maʻamau no nā mea pena ʻelua ma ka goethite a me ka Co-goethite.Ua paʻa mau ka pae adsorption i ka pae o ka pH i aʻo ʻia i ka wā he magnetite ka adsorbent.Ua ho'ohana 'ia ke kŘkohu capacitance mau (CCM) e kūpono i nā hopena ho'okolohua.ʻO nā paʻakikī ʻili i manaʻo ʻia mai ka ʻikepili adsorption ua kuʻikahi me nā kumu i loaʻa mai ka spectroscopy FTIR a me ka helu ʻana i ka mīkini molekala.He hana maikaʻi loa ko Goethite ma ke ʻano he adsorbent o Alizarin a me Eriochrome Blue Black R. ʻO ka loaʻa ʻana o kahi cation haole i Co-goethite ʻaʻole ia e hoʻomaikaʻi i nā hiki adsorption o goethite.Ma ka pH haʻahaʻa, ua like ka nui o Alizarin a me Eriochrome Blue Black R i hoʻopili ʻia ma goethite a me Co-goethite.Eia nō naʻe, ʻike ʻia kahi hilinaʻi kiʻekiʻe me ka piʻi ʻana o ka pH e Eriochrome Blue Black R. Ma ka magnetite, hōʻike ka adsorption dye i ka liʻiliʻi o ka pilina no nā mea ʻelua.Hiki i nā noʻonoʻo uila a me ka steric ke wehewehe i nā ʻano i loaʻa i ka adsorption o nā mea pena ʻelua ma nā ʻokiki hao ʻekolu i aʻo ʻia ma kēia hana.
