Abstract The results of investigation show that Baharia Barite, Contains : 98% BaSO4, 0.87% Fe2O3 and ).24% SiO2; whileEssel celestite contains 96.3% SrSo4, O72% SiO2, ).31% CaO and O.ll% MgO The possibility of isolation of the ternary complex in the system under investigation in solid form is largely dependent on the nature of the divalent transition metalion.(2)The divalent anions of the primary ligand (ADA-2)are coordinated to the central divalent transition metal ions as tridentate ligand. |
