In this way, experimental conditions such as aerosol gas flow rate and colloidal stability were optimized in order to use aqueous calibration curves in the slurry nebulization and to determine the chemical composition of a series of sols containing chemically synthesized size-tailored NiFe 2O 4 nanograms. Then, the results of direct sampling and those of conventional aqueous introduction analysis are compared, showing the efficiency of the proposed method.393-396engFerrite nanoparticleIcp-oesMagnetic colloidSlurry injectionColloidsFerritesFlow of gasesMagnetic materialsNanoparticlesFerrite nanoparticlesMagnetic colloidsSlurriesTrabalho apresentado em eventoAcesso aberto2-s2.0-345479660682-s2.0-34547966068.pdf
