which are important preconditions for
an efficient oil sorbent [17]. Based on these facts, there is the possibility
that the silkworm cocoon waste acts as a high performance
material for the sorption of oil. The silkworm cocoonwaste without
removal of sericin wasmilled, and the obtained flocculate material
(Fig. 1b) was used as a sorbent for oil in this study. The oil-sorption
capacity, rate and reusability of the silkworm cocoonwaste sorbent
(SCWS) were investigated.
