Study on the Syntheses of Ferrofluids by Different Iron Compounds and their Specific Adsorption Rate of Magnetic Fluid Hyperthermia

Abstract:

The highest SAR (specific adsorption rate) value of ferrofluid was found to be 28.5±1.9W/g, when prepared by using ferrous chloride tetrahydrate (FeCl₂•4H₂O) and iron(III)nitrate 9-hydrate(Fe(NO₃)₃• 9H₂O) with the 1:1 ratio of iron compound’s molarity. The SAR values of ferrofluids were found to be 62.0±6.5, 59.4±10.3, and 66.0±5.0 W/g, respectively, when prepared by using ferrous sulfate 7-hydrate (FeSO₄•7H₂O) and ferric chloride hexahydrate (FeCl₃•6H₂O) with the 1：2.5, 2.5：1, and 3：1 ratio of iron compound’s molarity . The SAR values of ferrofluids were found to be 66.6±7.0 and 63.5±6.0 W/g respectively, when prepared by using ferrous sulfate 7-hydrate (FeSO₄•7H₂O) and iron(III)nitrate 9-hydrate (Fe(NO₃)₃•9H₂O), with the 1：1, 1：1.5 and 1：2 ratio of iron compound’s molarity. The SAR values of ferrofluids were found to be 84.7±12.7, 93.4±14.2 and 89.2±6.4 W/g, respectively, when prepared by using ferrous chloride tetrahydrate (FeCl₂•4H₂O) and ferric chloride hexahydrate (FeCl₃•6H₂O), with the 1：1, 1：1.5 and 1：2 ratio of iron compound’s molarity .
