논문 초록 (Abstract)
A scoop net equipped with an underwater anti-oil-fouling (AOF) filter was tested for the cleanup of low-sulfur fuel (LSF) in support of a landmark decision made by the International Maritime Organization (IMO) in 2020. An underwater AOF filter (fabric/O-CS/PVA-KGM) possessing a partially dissoluble surface was prepared by the stepwise coating of oxidized carbon soot (O-CS) and polyvinyl alcohol/Konjac glucommannan (PVA/KGM) onto different fabrics. The effects of the molecular weight (MW) of PVA, thickness of the filter, and water temperature on the underwater AOF performance of the filter were investigated. Since the fabric (3 mm)/O-CS/L-PVA-KGM filter showed the highest water absorption capacity (6.23 g/g) and water content (96.4%) after 1 h, this filter showed the lowest amount of residual LSF (Abs: 0.004 at 275 nm) and the best long-term AOF stability after 30 cycles at 20 °C. This filter still showed excellent AOF performance (Abs: 0.008 at 275 nm) and high flux (66,793 L/m2h) at 4 °C due to high water absorption capacity/contents and large pores/relatively long multichannels, respectively.
