“…However, the q e values at the agitation speeds of 150, 200 and 250 rpm are fairly the same suggesting that the effect of agitation has plateaued at about 150 rpm. This effect can be attributed to the increase in turbulence and the decrease in boundary layer thickness around the adsorbent particles as a result of increase in the degree of mixing [46] . This result is also in agreement with that reported by Al-Qodah [47] and Ho et al [48] , for the adsorption of dyes onto activated clay and shale oil ash, respectively.…”

Problem statement:The aim of this study was to investigate the removal of methyl red, a mutagenic monoazo dye, from various aqueous solutions using banana pseudostem fibers of the size 212-350 micron. Approach: The parameters studied were the effect of pH, amount of adsorbent, contact time, concentration of adsorbate and agitation speed. Results: Equilibrium data were fitted to the Langmuir and Freundlich isotherm models. The data were best represented by the latter with an adsorption capacity and adsorption intensity of 0.351 and 0.302, respectively. Conclusion/Recommendations: Specific rate constants of the processes were calculated by kinetic measurements and a pseudo second order adsorption kinetics was obtained for all cases.

“…The ESM resides between the egg white and the inner surface of the eggshell (Tsai et al, 2006). The Hen Eggshell Membrane (HESM) consists of interwoven protein fibers and spherical masses (Tsai et al, 2008). The duck egg contains about 11% eggshell and ESM.…”

The eggshell membranes of ducks and hens were carbonized or activated with 4 wt% sodium acetate or zinc at 400-600°C. The carbonized or activated products were characterized by SEM-EDS, TEM, FTIR and XRD. It was found that the suitable activation temperature for eggshell membranes is 500°C with 30.03-35.26% yield. The activation performance of CH 3 COONa for eggshell membrane activated carbon production was higher than that of Zn metal. The CO 3 2-, Ca-O, C=C, Na-O and C-O functional groups have been formed on the surface of eggshell membrane activated carbon materials during both CH 3 COONa and Zn activation. Furthermore, CaO, MgO, Na 2 O and ZnO have also accumulated on eggshell membrane activated carbon materials with high content and regular dispersion. It was shown that the particles on the duck eggshell membrane activated carbon formed with Zn had weaker attachment on the surface than for duck eggshell membrane activated carbon formed with CH 3 COONa at same temperature. The XRD and TEM results revealed that the eggshell membrane activated carbons consist of an amorphous carbon matrix with some disordered graphite carbon matrix, spherical particles and nanofiber.

“…However, these egg shells can be used as an excellent adsorbent because of their porous nature; about 700 to 1,700 pores are present on the surface an egg shell [18,19] . The egg shells are also attractive as adsorbent due to their good mechanical properties and thermal stability [20] and already used as adsorbent for the removal of heavy metals [21] , phenolic compounds [22] , dyes [23] , and pesticides [24] .…”

Chicken egg shells were grinded and sieved to an exact particle size of 125 micron and treated with excess aqua regia and n-hexane to remove inorganic and organic impurities. Adsorption of oxalic acid from waste water was studied on treated powder egg shells by kinetics and batch adsorption techniques at different temperatures, 20ºC, 30ºC and 40ºC. The samples were characterized by BET surface area, scanning electron microscopy (SEM), and Fourier Transform Infra-red Spectroscopy (FTIR) and energy dispersive spectroscopy (EDS) techniques. The amount of acid adsorbed was determined with respect to initial acid concentration, equilibrium time and different acid concentration manually by titration method. Intra-particle diffusion, Elovich and Bhangam models were used for adsorption kinetics and thermodynamic parameters ΔH ≠ , ΔS ≠ and ΔE ≠ were calculated. The results obtained showed that adsorption process was spontaneous and entropy of adsorption had negative value. Freundlich, Langmuir, Tempkin and Harkins-Jura linear equations were used to investigate adsorption isotherms. This work will provide feasible routes for waste water treatment.
