Activated carbon production, impregnated in silver metal, used e.g. filter bed for liquids and gases, comprises preparing silver halide solution, pulverizing solution on activated carbon fog, heating for reduction and cooling

摘要

The production of activated carbon impregnated in silver metal having bactericidal properties comprises preparing a silver halide solution in ammonia (solution (A)), pulverizing the solution (A) on very fine fog on the activated carbon, in a reactor, under agitation, to obtain an average silver metal deposit determined in advance, heating the reactor content under reducing condition and cooling the activated carbon in the presence of continuous steam. An independent claim is included for the activated carbon impregnated in silver metal obtained by the above process.
