dc.description.abstract | Sulphuric acid-modified bagasse has been
used as low-cost adsorbent for the removal of methylene
blue (MB) dye from aqueous solution. In order to
remove organic compounds that contribute to chemical
oxygen demand (COD), pretreatment with thorough
washing of adsorbent using boiling distilled water was
performed instead of conventional washing using
distilled water at room temperature only. This has
resulted in the highest efficiency of color removal of
99.45% and COD reduction of 99.36% for MB dye
solution at pH 9. Effects of initial pH, dye concentration,
adsorbent dosage, temperature, and contact time have
been studied. The adsorption of MB dye was pH
dependent. Langmuir and Freundlich isotherm models
were tested on the adsorption data. The kinetic
experimental data were analyzed using pseudo-first
order, pseudo-second order, and the intraparticle diffusion
model in order to examine the adsorption mechanisms.
The adsorption process followed the Langmuir
isotherm as well as the Freundlich isotherm and pseudosecond-
order kinetic model. The process was found to
be endothermic in nature. | en_US |
