This research studied the application of fish bone
as a low-cost adsorbent for the removal of two basic dyes
(C.I. Basic Blue 41 and C.I. Basic Yellow 28) from textile
wastewaters. The surface morphology and functional
groups of the fish bone was studied by scanning electron
microscopy and Fourier transform infrared, respectively.
The experiments were designed in two methods: classical
method and response surface methodology (RSM). The
effect of operating parameters including pH, initial dye
concentration, adsorbent dosage, and inorganic salts was
investigated by both methods. The optimum conditions to
satisfy 75 % of dye removal for both dyes were predicted
by RSM method and the results were very close to the
experimental values. So, it was concluded that the fish
bone can be used as a low-cost adsorbent for dye removal
from effluents.
