TY - JOUR AU - Wu, F.C. AU - Tseng, R.L. T1 - Preparation of highly porous carbon from fir wood by KOH etching and CO"2 gasification for adsorption of dyes and... PY - 2006 JF - Journal of Colloid And Interface Science VL - 294 IS - 1 SP - 21 EP - 30 N2 - Fir wood was first carbonized for 1.5 h at 450@?^oC, then soaked in a KOH solution KOH/char ratio of 1, and last activated for 1 h at 780@?^oC. During the last hour CO"2 was poured in for further activation for 0, 15, 30, and 60 min,...
