Papaya wood has been shown to be highly effective in
removing heavy metals from aqueous solution. Among the
advantages of this new biosorbent are its rapid and high
adsorption–desorption property and reusability in repeated
cycles. Furthermore, papayawood is very cheap, easily available
and abundant source of biomaterial generated as a waste
from papaya tree (C. papaya), when completes its fruit bearing
life, grown in all tropical and subtropical countries and at
present has no commercial value. The study revealed that this
new biosorbent could be used as a tool for the development
of low-cost biomaterial-based polishing treatment of heavy
metal waste.
