Two samples of the defectdouble perovskites with general formula Sr2CaNbO5.5 and Sr2CaTaO5.5 were synthesized and their cap abilities in the removal of neutral red dye investigated. Both samples have faced cubic perovskite-type structure in space group Fm3m. The replacement of Nb5+ by Ta5+ has influ…
