In present study adsorption capacity of waste materials of Daucus carota plant (carrot stem powder: CSP and carrot leaves powder: CLP) was explored for the removal of methylene blue (MB) malachite green (MG) dye from water.
The morphology and functional groups present were investigated by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy.
The operating variables studied were pH, adsorbent dose, ionic strength, initial dye concentration, contact time and temperature.
Equilibrium data were analysed using Langmuir and Freundlich isotherm models and monolayer adsorption capacity of adsorbents were calculated.
Kinetic data were studied using pseudo-first and pseudo-second order kinetic models and the mechanism of adsorption was described by intraparticle diffusion model.
Various thermodynamic parameters such as enthalpy of adsorption DH, free energy change DG and entropy DS were estimated.
Negative value of DH and negative values of DG showed that the adsorption process was exothermic and spontaneous.
Negative value of entropy DS showed the decreased randomness at the solid–liquid interface during the adsorption of MB and MG onto CSP and CLP.
