Abstract

Ferit nanopartikel M0.Fe204 dengan M = Fe, Ni, Zn , dipersiapkan untuk penibuatan ferofluida dengan metode kopresipitasi. Ferofluida merupakan bahan magnet cair koloid yang terdiri dari partikel-partikel magnetik yang berukuran nano yang dilapisi oleh surfaktan . Karakterisasi bahan dilakukan dengan pengujian VSM (Vibrating Sample Magnetometer ), dan SEM (Scanning Electron Microscope). Dianalisis pengaruh doping yang diberikan dan surfaktan yang digunakan terhadap sifat magnetik ferofluida. Ferofluida dengan M = Fe mempunyai sifat kemagnetan paling tinggi dengan nilai Ms = 52,851 emu/gram, Mr = 15,279 emu/gram dan Hc = 0,0410 tesla. Penggunaan surfaktan Tetrametil-amonium-hidroksida surfaktan menghasilkan ferofluida yang lebih kuat dibandingkan dengan penggunaan surfaktan asam oleic-cis.

M 0.Fe204 with M = Fe, Ni, and Zn ferrites nanoparticles for the preparation of terrofluids have been synthesized by chemical co-precipitation method. Ferrofluids colloidal suspensions of magnetic nanoparticles with surfactants used Characterizations using Vibrating Sample Magnetometer ( VSM )and Scanning Electron Microscope (SEM ) have been utilized. Magnetic properties of ferrofluids with diferrent surfactants and doping effect are discussed. The ferrofluids which M = fe has the highest magnetic properties with Ms = 52,851 emu/ g, Mr = 15,279 emu/g dan Hc = 0,0410 tesla. Ferrofluids with of tetramety amonium hydroxide surfactants generally have stronger magnetic responses than those with oleic-cis acid.
