In this study, Carob powder was used as the
adsorbent to remove the aqueous solvent paint. The as-prepared carob powder was
structurally characterized by scanning electron microscopy(SEM), transmission
electron microscopy (TEM). In the experiments, six inputs pH (2-8), ultrasound
frequency (50-150 hz), particle size (50-150 µm), adsorption temperature (25-40
°C), solution concentration (10-30 mg/L) and adsorption time (120-360 min) were
examined using the statistical Box-Behnken design with parameters. The
quadratic model was selected with the coefficient (R2) found 0.8899
and 0.9830 in the experimental data. Under the optimum conditions (pH= 5.85,
ultrasound frequency= 36.40 Hz, particle size= 137.63 μm, adsorption
temperature= 25.38℃, solution
concentration= 29.30 mg/L and adsorption time= 267.63 min) 6 different
experimental setups were prepared. The average amount of dye recovery obtained
from the test results was found to be 256,4355 mg/g. As a result of the present
work, it was seen that carob powder could be a strong alternative adsorbent for
methylene blue removal.
