| dc.description.abstract | In this work, Tilapia (Oreochromis niloticus) fish scales were used for the development
of an economical biochar (FSB) by slow pyrolysis at 600 oC. The FSB was characterized
using energy dispersive x-ray (EDX), x-ray fluorescence (XRF), x-ray diffractometry
(XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM)
techniques. The potential of FSB for the uptake of copper ions from water was examined
as a function of initial concentration. Adsorption data were treated using eleven
adsorption isotherms, and the most applicable equation obtained by comparison of the
coefficient of determination (R2
) values calculated by nonlinear regression method.
Equilibrium data were best explained by Langmuir isotherm denoting monolayer
adsorption of Cu(II) ions onto FSB. The FSB’s maximum adsorption capacity was 39.39
