“…It is observed that there was an interference of boundary layer for both metal ions. Itodo et al (2009) reported that deviation of the plot of q t against t 0.5 shows that intra-particle transport is not the only rate limiting step, possibly adsorption occurred on the surface of the adsorbent or there was movement of metal ions through the particle-sample interface onto the pores of the adsorbent. Similar results were reported by Badmus et al(2007).…”

ABSTRACT:In this paper agricultural waste; Canarium schweinfurthii was explored for the sequestering of Fe and Pb ions from wastewater solution after carbonization and chemical treatment at 400 o C. Optimum time of 30 and 150 min with percentage removal of 95 and 98% at optimum pH of 2 and 6 was obtained for Fe and Pb ions. Kinetics model followed pseudofirst order as sum of absolute error (E ABS ) between Q e and Q c greater than that of pseudo second order. Parameters evaluated from isothermal equation (Freundlich and Langmuir) showed that K L and Q O for Fe > Pb and R 2 for Langmuir> Freundlich. The study reveals the suitability of the adsorbent for sequestering of Fe and Pb ions from industrial wastewater. ©JASEM

“…An isotherm is a functional expression for the variation of adsorption relative to the concentration of adsorbate in the bulk solution at constant temperature [4]. It describes the relation of between the adsorbate retained by the activated carbon and the adsorbate equilibrium concentration [4].…”

“…It describes the relation of between the adsorbate retained by the activated carbon and the adsorbate equilibrium concentration [4]. It was defined as a graphical representation showing the relationship betweenthe amounts of the adsorbate in mg, adsorbed by a unit weight of adsorbent in g for example activated carbon and the amount of adsorbate remaining in a test medium of equilibrium.…”

“…Sorption isotherm is dependent on data that are specific for each system and the isotherm must be determined for every application. An adsorption isotherm besides providing information on the course taken by the system under study in a concise form, it also indicates how efficiently an adsorbent is in terms of the economic feasibility of the carbons in commercial applications and for the specific solute [5]. Researchers have studied the adsorption of surfactants onto some mineral surfaces in aqueous medium as prelude to the selective flotation of the minerals from their ores and have established that mineral flotation is an interfacial phenomenon brought about fundamentally by the selective adsorption of a surfactant onto a mineral surface.…”

Chemical modification of chitosan has become increasingly essential due to chitosan versatility that enables the material to be easily modified in a way of increasing its properties in adsorption processes. In this investigation, chitosan solution was cross‐linked with glutaraldehyde the cross‐linked solution was used in producing the beads and thereafter grafted with ethylene acrylic acid. The chemical functionalities of the beads were obtained by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), X‐ray diffraction (XRD) and Thermogravimetric analysis (TGA). Adsorption of Pb2+, Cu2+, Ni2+, Zn2+, Cr6+ and Cd2+ ions from single component aqueous mixture by grafted cross‐linked chitosan beads (GXXB) was studied as a function of pH, temperature, initial concentration, contact time, agitation speed and ionic strength. Equilibrium data was obtained from the adsorption experiment, the data were applied in isotherm, thermodynamics and kinetic studies. The Langmuir, Temkin and Dubinin‐kaganer‐Radushkevich (DKR) model were successful in describing the isotherm data for the considered metal ions while the Freundlich model was not efficient in describing the experimental data. Pseudo‐second order and intra‐particle model described the kinetic data quite well. Thermodynamic parameters such as Gibb's free energy change (∆Go), enthalpy change (∆Ho) and entropy change (∆So) were calculated and the results showed the adsorption of Pb2+, Cu2+, Ni2+, Zn2+, Cr6+ and Cd2+ ions onto GXXB is spontaneous and endothermic in nature. Regeneration of the used adsorbent was effective for the studied metal ions.
