"Comparative study of methods in the synthesis of magnetite between hydrolysis\r\noxidative and co-precipitation method has been done. Hydrolysis oxidative method was\r\ndone by added the solution of KOH (22.45 g) and KNO3 (3.23 g) in water (120 ml) into\r\nsolution of FeSO4∙7H2O (40.00 g) in water (280 ml) in the N2 atmosphere at 90 oC. Coprecipitation\r\nmethod was done by added dropwise the solution of NH4OH (1 M) into 200\r\nmL of FeSO4\r\n.7H2O and FeCl3\r\n.6H2O solutions (molar ratio 1:2) with total concentration of\r\n6 M until pH 11.5. The solid phase formed in each method was then filtered, washed,\r\nand dried. The characterization of product by XRD and FTIR methods indicated that coprecipitation\r\nmethod produced higher in rendemen (81.25%) than that of hydrolisis\r\noksidative method (71.26 %). In addition, the size of magnetite produced by coprecipitation\r\nmethod (15.7 nm) smaller than that of produced by co-precipitation method\r\n(27.8 nm)."^^ . "2014-05" . . .
