Abstract EN
This research studies the characterization of activated carbon from tamarind seed with KOH activation.
The effects of 0.5 : 1–1.5 : 1 KOH : tamarind seed charcoal ratios and 500–700°C activation temperatures were studied.
FTIR, SEM-EDS, XRD, and BET were used to characterize tamarind seed and the activated carbon prepared from them.
Proximate analysis, percent yield, iodine number, methylene blue number, and preliminary test of Fe(III) adsorption were also studied.
Fe(III) adsorption was carried out by 30 mL column with 5–20 ppm Fe(III) initial concentrations.
The percent yield of activated carbon prepared from tamarind seed with KOH activation decreased with increasing activation temperature and impregnation ratios, which were in the range from 54.09 to 82.03 wt%.
The surface functional groups of activated carbon are O–H, C=O, C–O, –CO3, C–H, and Si–H.
The XRD result showed high crystallinity coming from a potassium compound in the activated carbon.
The main elements found in the activated carbon by EDS are C, O, Si, and K.
The results of iodine and methylene blue adsorption indicate that the pore size of the activated carbon is mostly in the range of mesopore and macropore.
The average BET pore size and BET surface area of activated carbon are 67.9764 Å and 2.7167 m2/g, respectively.
Finally, the tamarind seed based activated carbon produced with 500°C activation temperature and 1.0 : 1 KOH : tamarind seed charcoal ratio was used for Fe(III) adsorption test.
It was shown that Fe(III) was adsorbed in alkaline conditions and adsorption increased with increasing Fe(III) initial concentration from 5 to 20 ppm with capacity adsorption of 0.0069–0.019 mg/g.
