An yi nazarin tsarin tallan kayan rini biyu a matsayin aikin pH akan nau'ikan adsorbents guda uku (goethite, Co-goethite, da magnetite).An lura da halayen adsorption na anionic ga duka rini akan goethite da Co-goethite.Matsayin adsorption ya kasance koyaushe a cikin kewayon pH da aka yi nazari lokacin da adsorbent ya kasance magnetite.An yi amfani da ƙirar ƙarfin ƙarfin koyaushe (CCM) don dacewa da sakamakon gwaji.Kamfanonin saman da aka tsara daga bayanan talla sun yi daidai da tsarin da aka samu daga spectroscopy na FTIR da lissafin injiniyoyi.Goethite yana da kyau sosai a matsayin adsorbent na Alizarin da Eriochrome Blue Black R. Kasancewar cation na waje a cikin Co-goethite baya inganta iyawar tallan goethite.A low pH, adadin Alizarin da Eriochrome Blue Black R da aka tallata akan goethite da Co-goethite sunyi kama.Duk da haka, dogara mafi girma tare da karuwar pH yana lura da Eriochrome Blue Black R. A kan magnetite, daɗaɗɗen launi yana nuna ƙarancin kusanci ga duka rini.La'akari da lantarki da stric za su iya bayyana yanayin da aka samu a cikin tallan rini biyu akan nau'in ƙarfe uku da aka yi nazari a cikin wannan aikin.
