Abstract:
... In this study, the effect of packing density, oil type and temperature on the sorption kinetics behavior of cattail fiber was investigated based on Washburn theory by capillary rise test. It was found that higher packing density resulted in lower oil sorption capacity due to the less available space among fibers. The sorption coefficient to different oils which represented the sorption rate exhibi ...
