| description | Water sources such as rivers, lakes, groundwater and seas that located
nearby to textile industries can be easily polluted if direct discharge of dye
wastewater to the environment is occurred. Adsorbent such as activated
carbon particularly produced from agrowaste has been found to be suitable
for this purpose. In this study, tamarind seed based activated carbon
(TASAC) and jackfruit seed based activated carbon (JASAC) were prepared
by using physiochemical activation. It consisted of potassium hydroxide
(KOH) impregnation, CO2 gasification and microwave irradiation. A study
of batch adsorption for methylene blue (MB) and remazol brilliant blue R
(RBBR) were carried out to determine the performance of TASAC and
JASAC. Central composite design (CCD) was used to evaluate the optimum
preparation conditions of radiation time, radiation power and impregnation
ratio (IR) for TASAC and JASAC. The optimum conditions for TASAC
were 440 W, 2.0 min and IR 0.5 while for JASAC was 440 W, 2.0 min and
IR 0.6, which resulted MB removal of 70.4% and 83.2%, respectively; RBBR
removal of 62.7% and 75.6%, respectively and yield of 21.8% and 22.5%,
respectively. TASAC and JASAC have high surface area (>869 m2/g), pore
volume (> 0.40 cm3/g) and fixed carbon content (>76%). The TASAC and
JASAC have heterogeneous type pore size in mesoporous region. The effect
of initial dye concentrations (25-300 mg/L), contact times (0-24 hours) and
solution temperatures (30-60oC) were determined. The MB and RBBR
adsorption by TASAC and JASAC were increased as the initial dye
concentration and contact time increased. The adsorption equilibrium data
for both dyes onto TASAC and JASAC were best fitted by Freundlich
model. Meanwhile, the kinetic data was best represented by the pseudo firstorder
kinetic model. |
