Popis: Titano-silicate (TiSi) and in-situ dopped composites were obtained by precipitation technique. The composition of these materials was established by IR, XRD, TGA&DTA, and XRF. The capacity for Co(II), & Cd(II) ions revealed that Co-TiSi & Cd-TiSi is a higher capacity than those obtained for TiSi by 1.81, & 1.41 values, respectively. To explore the separation potentiality of Co-TiSi for studied cations distribution coefficients in HNO3 were estimated. Langmuir isotherm model is the most representative for discussing the sorption process with a maximum sorption capacity of 16.02, and 10.96 mg/g for Co(II), & Cd(II) ions, respectively. Co-TiSi is suitable for the column technique for the recovery of studied cations. The investigation proved that Co-TiSi composite is suitable for the uptake of the studied ions from liquid solutions and could be considered as potential material for the refining of effluent polluted with these ions.
