| description | This study focuses on the removal of cationic dye (methylene blue) from aqueous
solution using agricultural waste as alternative adsorbents. The main aim of this
study was to investigate the adsorption of methylene blue (MB) onto durian peel
(DP), banana leaves (BL), pineapple stem (PPS), pineapple leaves (PPL), papaya
stem (PYS) and papaya leaves (PYL). The effects of operating conditions such as
initial dye concentration (50-500 mg/L), contact time, pH (2-10) effect, and
temperature (30-50 oC) on adsorption of MB were studied in batch process.
Equilibrium data for the adsorption of MB on all the adsorbents were analyzed by the
Langmuir, Freundlich and Tempkin isotherm models. It was found that Langmuir
isotherm model fits the data very well for all the adsorbents. Pseudo-first-order,
pseudo-second-order and intraparticle diffusion were tested to investigate the
adsorption mechanism. |
