ABSTRACT:
A process is described for the production of granular algal adsorbents having an average particle size of 0.1 to 10 mm, wherein an aqueous solvent is added to a mixture of 5 to 90 parts by weight of activated carbon having a particle size not larger than 2 mm and 10 to 95 parts by weight of algal powder composed of Chlorella and/or Spiruline, followed by granulation and drying. Adsorbents made by this process are effective filters for the removal of toxic and odiferous materials in smoke and air and are particularly useful in cigarette filters.
