Abstract

Filter material for removing hydrogen cyanide and hydrogen sulphide from tobacco smoke comprises adsorbent granules having a specific surface area exceeding a million square centimetres per gram, a particle size between 8 and 50 mesh, and impregnated with finely-divided iron and zinc oxides, each oxide being present in an amount not less than 1% nor more than 13% by weight of the adsorbent and the two oxides together not exceeding 14% by weight thereon. The adsorbent granules are activated charcoal and one or both oxides is preferably present in an amount between 4% and 6%. The filter material may be incorporated in a cartridge, for example in a pipe, or may be enclosed between two conventional cellulose acetate filters in a cigarette mouthpiece. The filter material is made by soaking the adsorbent material in an aqueous mixed solution of (a) zinc carbonate, zinc oxide or zinc acetate, (b) a ferric ammonium citrate, ferric citrate, ferrous ammonium citrate, ferrous citrate, ferrous ammonium acetate, ferrous acetate or ferrous ammonium carbonate, and (c) ammonia, and heating the adsorbent material to decompose the adsorbent salts. The heating may be carried out in air at temperatures between 175 and 350 DEG C.
