Abstract
In this study, the denim fiber scraps were
reused as an alternative low-cost sorbent for the removal of
heavy metals Pb2+, Cd2+, Zn2+ and arsenic from aqueous
solutions. Results showed that this textile waste was an
effective sorbent for the removal of these heavy metal ions
and offered a better removal performance than those
reported for other synthetic and natural sorbents such as
activated carbons and zeolites. On the other hand, raw and
metal-loaded denim wastes were also useful for the
removal of arsenic (V) from aqueous solutions and their
sorption capacities were higher than 1.5 mg/g. In particular,
the presence of Pb2+ ions on the surface of denim
wastes improved significantly its arsenic (V) sorption
performance. In summary, the reuse of denim textile
wastes in wastewater treatment can be considered as an
eco-friendly application that could be useful for waste
management and also for reducing the production costs in
this important industrial sector.
