Developing Wood-Based Activated Carbon Fibers Paperboard for thermal absorption filtration of oil fume

This study evaluated Wood-Based Activated Carbon Fibers Paperboard (WACFP) made of different proportions of wood-based activated carbon fibers (WACFs) with wood pulp as the oil fume absorbing material. The WACFPs, in basis weights of 180 g/m² and with 0,10, and 40% WACFs, absorbed peanut oil fume at the smoke point, absorption saturation was reached at 80,110, and 120 min, and oil fume absorption was 0.0203-0.0304 g/cm². The WACFPs, in basis weights of 360 g/m² and with 0, 10, and 40% WACFs, reached absorption saturation at 210, 250, and 260 min, and oil fume absorption was 0.0424-0.0604 g/cm². For Ames test, the oil fume absorbed by WACFPs extracted by methanol at concentrations higher than 0.10 mg/plate had cytotoxicity with Salmonella typhimurium TA98 (±S9) and TA100 (±S9); and the Mutagenicity ratio of methanol oil fume extracts at concentration of 0.05 mg/plate for Salmonella typhimurium TA98 (±S9) and TA100 (±S9) were higher than 2, representing very high mutagenicity for Salmonella typhimurium TA98 and TA100. According to the GC-MS analysis of the n-hexane soluble fraction of oil fume, the trans-trans-2,4-decadienal (t-t-2,4-DDE) was the main mutagenic compound of peanut oil fume probably.
