Resumo
The demand for low cost and effective materials to
remove contaminants such as residues of oil spills has encouraged
studies on new biosorbents produced from wastes.
Considering the overgeneration of fishing residues and the
necessity to provide an alternative purpose for such materials,
this study aimed to evaluate squid gladius and its derivatives
(β-chitin and chitosan) as sorbents to remove marine diesel oil
(MDO) from fresh and artificial seawater. It was also executed
an attempted to improve their performances through a highintensity
ultrasound treatment (UT-gladius and UT-β-chitin).
All sorbents removed MDO at both salinities. Contact surface
area, salinity, and water retention seemed to play a key role in
the outcomes. UT-β-chitin’s performance was significantly
superior to β-chitin’s and chitosan’s in MDO removal at salinity
0, as well as at salinity 30, where gladius and UT-gladius
also excelled. Ultrasound treatment improved the oil removal
performance of UT-β-chitin by increasing its contact surface
area. This is the first report on the efficiency of gladius and
UT-β-chitin for such purpose, and brought up huge possibilities
and new questions that can lead to the achievement of
biosorbents of great efficiency.
