摘要：

The paper presents the theoretical aspects regarding the magnetogravimetric purification of ferrofluids both in the process of preparation and for their reconditioning from impurities. An experimental device used for magnetogravimetric purification is described together with experiments on some samples of oil-based ferrofluid that became impure with non-mixible solid, liquid, magnetic and nonmagnetic ingredients. The experiments resulted in a complete purification of the ferrofluid samples.
