The adsorption of Cu (II) from aqueous solutions using coconut shell
modified powder was investigated in batch experiments. The surface
charge of the adsorbent was determined. The points of zero charge (PZC)
of the adsorbents (pH(PZC)) were 4.5, 2.0, and 2.0 to raw coconut (RC),
raw coconut alkalized (RCA), and coconut shell modified with tannic acid
(TCA) adsorbent, respectively. Batch experiments were performed under
kinetic and equilibrium conditions. The kinetic data were analyzed using
a pseudo second-order, and Elovich equation. Adsorption equilibrium data
were investigated using the Langmiur, Freundlich, Temkin, and
Dubinin-Raduschevich (D-R) isotherm models. It has been found that
chemically modified coconut shell (TAC) affected performance when
compared with unmodified coconut shell (RC). Kinetic studies showed that
the adsorption followed a pseudo-second-order rate model. Biosorption
kinetics of Cu(II) on the adsorbent TCA was rapid such that almost 90%
of Cu(II) were adsorbed within 80 min. (C) 2014 Wiley Periodicals, Inc.
