摘要:In this article millingtonia hortenesis leaves, one of the herbal plant materials, available in plenty quantity in india, was chosen as an biosorbent to clutch out crystal violet dye in aqueous media. An equilibrium feature of leaves was scrutinized by executing the experiments in batch adsorption mode. Adsorption models like Langmuir, Freundlich and Temkin were examined to portray briefly the reaction sequences at its equilibrium phase. Langmuir equation was found to have the highest value of R compared with other models. Furthermore, it was found that leaves have an adsorptive capacity of 40 mg/g and show favorable adsorption of CV dye with separation factor (R 1). In addition, pseudo-first- order, pseudo-second order and intra-particle diffusion were used to study the kinetics of MB adsorption onto leaves. Adsorption process undergoes pseudo-second order kinetic as bear out by its towering Rvalue and also inferred by the low value of sum of squared error (SSE percentage). Results pointed out that intra-particle diffusion model could never orients and the adsorption process is spontaneous as indicated by the negative value of the .
