To examine the useability of phenol resin as the raw material of active carbon, phenol resin was carbonized under the appropriate conditions, and specific surface area were measured.
The adsorptivity of the carbonized phenol resin was measured using iodine, permanganate, and methylene blue respectively.
Further specific surface area was measured by gas chromatography.
As a result, it was found that specific surface area of the carbonized phenol resin was a little greater than that of the ordinary active carbon, and the optimum condition of the carbonization of phenol resin were one hour at 1,000 ℃.
