摘要: The sorption of Safranine onto the Archis hypogaea L. (groundnut) shell (GNS) has been studied in terms pseudo first order, second Elovich and intraparticle diffusion chemical processes. batch model, based on assumption a order mechanism used to predict rate constant equilibrium capacity with effect mass adsorbent, initial dye concentration, pH contact time. rates were found be conforming kinetics good correlation. Batch isotherm studies for described by Freundlich Langmuir equation. In adsorption isotherms, fits well experimental data having r 2 > 0.9956. maximum observed was 172.14 mg/g. values dimensionless separation factor RL are 0 < 1 indicating that favorable adsorption. adsorbent also characterized FTIR, XRD...
