Claims9
A method of making an adsorptive material which is in shaped discrete pieces comprising mixing active carbon powder with an aqueous solution of sodium silicate to form a moist mixture, forming the moist mixture into shaped discrete pieces, drying the pieces, immersing the pieces in a silicate-insolubilizing reagent until the silicate-content of the pieces has become insolubilized, washing the pieces with water, and drying the pieces at a temperature of at least 100.degree. C.
