摘要：

The surface area characterization of several woodpulps by humidity adsorption was discussed. It was found that the surface area was same regardless of the ionizable groups being in basic or acidic form. The analysis suggested that the estimation of specific surface area should be determined at the end of the first-order kinetic regime of adsorption.
