| Research Abstract |
The wastepaper pulp contents in recycled-paper samples were evaluated by image analysis of images from a fluorescence microscope, and they agreed well with the actual wastepaper pulp contents. Also the mean intensity of the images taken by confocal scanning microscopy had a strong correlation with the wastepaper pulp content.
In order to develop alternative uses of wastepaper, the pore structure and the adsorbability of activated carbon prepared from wastepaper were compared with those of commercial activated carbons. The amounts of Bisphenol A adsorbed in the range of 0. 1μg/l. 500 mg/l were higher in the kraft bag activated carbon than in commercial activated carbons.
