Abstract:
This study describes preliminary study of
tamarind seeds kernel powder as natural coagulant for color
removal of drimarene dark red (DDR) synthetic wastewater
(20 mg/L). The effect pH (2-7), dosage (1-3 g/L), and their
interactions were investigated using general factorial design.
The seeds powder was also characterized using Fourier
Transform Infrared Spectroscopy (FTIR) to observe the
possible active coagulating agent in this study. It was found
that the seeds powder contained protein that could act as
coagulant. Dosage, pH, and their interactions were found to be
statistically significant to the removal of DDR. Highest removal
of 84.60% was obtained at pH 3 and dosage 3 g/L.
