| dc.description.abstract | The production of pomegranate peel based activated carbon (PPAC) through microwave assisted KOH activation has been successfully investigated. PPAC produced was used for removal of malachite green (MG) and remazol brilliant blue reactive (RBBR) dyes from aqueous solution. The PPAC has high surface area of 941.02 m2/g and demonstrated heterogeneous mesoporous type of pore structure with a presence of various functional groups on the PPAC’s surface. The effects of adsorbate initial concentration (50-500 mg/L), contact time (0-24 h), solution temperature (30-60oC) and solution pH (2-12) were evaluated through batch adsorption test. All dyes adsorption uptakes increased with increasing temperature, initial dyes concentration and contact time. Adsorption of MG and RBBR dyes onto PPAC were best fitted by Freundlich model. Adsorption kinetic of MG and RBBR dyes onto PPAC were best fitted by pseudo-second-order kinetic model. From the thermodynamic study, the MG and RBBR adsorption onto PPAC were physically controlled type, spontaneous and endothermic in nature. From the mechanism study, the adsorption rate was governed by film diffusion mechanism. | en_US |
