Abstrakt
In this study,
continuous biosorption
-
desorption cycles in a fixed
-
bed column were
performed to evaluate the extended use of sphagnum peat as biosorbent material to remove Zn(II)
ions from aqueous solutions. Biosorption
-
desorption studies revealed that the sphagnum peat
as
biosorbent could be regenerated using 0.1M HCl as eluting agent with more than 70% recovery
in four successive biosorption
-
desorption cycles. The results showed that the sphagnum peat
should be used as an alternative, effective and low
-
cost biosorbent
for Zn(II) ions removal from
polluted aqueous solution.
