Adsorption of methylene blue dye over the adsorbent derived from Sapindus seed hull (S) and Camelina (C) is studied. Batch adsorption study on both adsorbents is compared as a function of various parameters such as time, initial concentration and temperature. Langmuir and Freundlich models were fitted to the equilibrium data of methylene blue dye adsorption. Kinetics was evaluated using pseudo-first-and second-order models. Weber Morris model helped to understand the intraparticle diffusion during adsorption of methylene blue molecules. Thermodynamic analysis on both adsorbents revealed the spontaneity of the process. The relative study illustrated a comparison in adsorption capacities among both the adsorbents. Morphology explicated the surface characteristics of both the sorbents. Fourier transform infrared spectroscopy spectrum revealed a variety of functional groups on adsorbents' surface.
Adsorption of malachite green dye over the adsorbents (Ad) derived from Sapindus seed hull (S) and Camelina (C) after treatment with sulphuric acid is studied. Batch adsorption study on both Ad is compared as a function of various parameters such as pH, time, initial concentration and temperature. The isotherm data is found to be best presented by Langmuir model for both adsorbents. Separation factor (R L ) revealed a favorable adsorption. Further, the rate of adsorption followed pseudo-first order kinetics. The intraparticle diffusion model facilitates to understand mass transfer in adsorption of dye molecules. Thermodynamic analysis on both Ad revealed the spontaneity of the phenomena at higher temperature. The comparative study illustrated higher adsorption capacity of CAd in comparison to SAd.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
