dc.description.abstractIn this study the efficiency of low cost eco-friendly carbon adsorbent prepared from Bauhenia racemosa seed (BRSC) was analysed for the removal of crystal violet (CV) dye from aqueous solution. Kinetics and thermodynamic parameters of the adsorption of crystal violet dye were evaluated. Adsorption kinetics is an important parameter as it provides significant details, such as reaction pathways and mechanism of the reactions. The adsorption kinetics of crystal violet dye onto Bauhenia racemosa seed followed Pseudo second order reaoon model. The intraparticle diffusion study shows that the rate constant for intraparticle diffusion (K^) increased with increase in initial concentration of crystal violet dye solution. The results of the thermodynamic studies revealed that the adsorption of crystal violet dye onto Bauhenia racemosa seed was spontaneous and endothermic in nature. The positive value of entropy change showed increased randomness during adsorption.en_US
