had a marked and linear effect
on the resulting adsorbent capacity, particularly in the case
of wood furniture waste chars. The best activation temperature
for the wood furniture chars was 8508C. Higher
temperature yielded too high burn-off levels. After 10 h.
of soaking time, the best-activated material was produced
yielding a highly microporous solid with a high surface area
(855 m2/g) and a high dye adsorption capacity with a mass
loss of 63%. Such values compared well with similar work
conducted using more conventional pyrolysis methods. For
example, Dalai et al. [14] achieved surface areas of 300–
650 m2/g, with mass loss of 40–90%, using a bench scale
