Samples of magnetic carriers of medicine for oncology (doxorubicine) have been obtained by the method of pulse electrolytic erosion of iron in liquid media (water, solutions of phosphoric acid and ethyl alcohol, hexane). It was shown that the sample obtained in hexane possesses the highest adsorptive doxorubicine capacity with its chemical transformation at desorption. It was ascertained that chemical transformation is observed for the sample obtained in hexane. This sample is well-dissolved in human blood plasma. Maximal dissolution time and possible iron removal from organism does not exceed 10 days.
