Isotherms, steady state flows, the four time-lags, the kinetics of sorption and of the approach to the steady state of flow have been measured and analysed to investigate the properties of a graphitized carbon membrane. Sorption isotherms determined on the membrane in situ by a kinetic pro­cedure involving the time-lags and steady state flows were in agreement with isotherms determined by a standard procedure. Analysis of the time-lag and other results left the possibility of a small dependence of the diffusion coefficient, D , upon positional coordinate or upon time, but the dominant influence upon D was its dependence upon concentration, C . Differential diffusion coefficients increased very rapidly with C outside the range of the Henry law. Uptakes of diffusant in the steady state of flow, measured directly, through time-lag measurements and from steady state concentration contours across the membrane were in good agreement.

Abstract Drainage canal sediments in an industrial park are generally dredged to landfill in Taiwan. The objective of this study was to evaluate feasibility employing the sediment as an adsorbent for removal of dye. The sediment contained approximately 10% of organic matter and little heavy metals. Infrared (IR) analysis revealed that carboxyl was the most important functional group for methylene blue (MB) sorption. Canal sediment could remove the most MB from water at pH 8.0 and this removal increased with increasing temperature. The MB sorption was well described by the Langmuir, Dubinin–Radushkevich, and Temkin sorption isotherms at 10°C, but it showed good compliance with Freundlich isotherm at 25°C and 40°C. The MB adsorption was a spontaneous and endothermic reaction; its maximum calculated adsorption capacity (Qm) was 56.0 mg g−1 at 10°C by the Langmuir isotherm. The calculated values of enthalpy (ΔH°) and entropy (ΔS°) are 14.6 kJ mol−1 and 149.2 kJ mol−1, respectively. Only pseudo-second-order adsorption kinetic model successfully described the kinetics of MB onto the sediment at different operation parameters. Activation energy of MB adsorption calculated from Arrhenius equation was 16.434 kJ mol−1, indicating the binding between canal sediment and MB was a physical adsorption.
