ABSTRACT:
The purification agent is constituted by a pulverulent mineral solid, on the surface of the constituent particles of which chains of polymers are fixed by grafting. The agent is useful for the purification of waters polluted for example by organic impurities such as hydrocarbons, and may be applied to the cleaning of systems which have contained petroleum.
