FIELD: medicine, pharmaceutics.
SUBSTANCE: present invention refers to pharmacology, nanomaterials and nanotechnology, and concerns a method for selective final purification of nanodiamonds to remove foreign nitrate ions and sulphur compounds to be used in pharmaceutics; the method implies that charge-free nanodiamond powder is treated with alkaline water of the concentration of 0.01-1 mole/l at 20-100°C; the prepared suspension is then decanted and centrifuged; the precipitation is washed with water using ultrasound, separated and dried.
EFFECT: higher effectiveness of the method.
