“…It has been reported in the literature that different adsorption equilibrium constants (K) are obtained with different isotherm models [11,12,23,24,26,39,50,[58][59][60][61]. The thermodynamic parameters of adsorption can be estimated from K g (the Liu equilibrium constant), as previously reported in the literature [11,26].…”

A B S T R A C TChemically oxidized pineapple fruit peel biomass has been used as a biosorbent for Cd(II) and Pb(II) removal from aqueous solutions. Fourier transform infrared spectroscopy and scanning electron microscopy techniques were used to characterize the treated pineapple fruit peel. The biosorption efficiency of pineapple fruit peel for Cd(II) and Pb(II) was greatly enhanced after chemical oxidation probably due to introduction of carboxylic and hydroxyl groups onto the biosorbent surface. Biosorption kinetics for both metals was well described by pseudo-second-order kinetic equation and intraparticle film diffusion. Langmuir, Freundlich, and Temkin isotherm models were applied to the biosorption equilibrium data and best results were obtained with Langmuir isotherm model. Maximum monolayer biosorption capacity was found to be 42.10 and 28.55 mg g −1 for Cd(II) and Pb(II), respectively. Thermodynamic study indicates that the biosorption was exothermic and the spontaneity of the process decreases with the increase in solution temperature.

“…The peaks at about 1600 cm À1 generally tend to be found in various activated carbons but cannot be assigned exactly (Sabio et al, 2004). It is implied from various studies that the bonds around 1600 cm À1 would be assigned to C¼C in aromatic skeleton (Sabio et al, 2004;Wang et al, 2012;Wang et al, 2013) or C¼O of carbonyl groups (Liu et al, 2010;Lalhruaitluanga et al, 2010;Wang et al, 2013). The peak at 1640 cm À1 was probably related to C¼O vibration, which would be caused by the reduction of carbonyl groups under the condition of higher carbonization temperatures.…”

“…On the other hand, the peak located at 1580 cm À1 appeared as a shoulder with the increase in carbonization temperature. The peak at 3450 cm À1 was attributed to the O-H stretching vibration (Lalhruaitluanga et al, 2010;Wang et al, 2012). The peaks at about 1600 cm À1 generally tend to be found in various activated carbons but cannot be assigned exactly (Sabio et al, 2004).…”

Bamboo chars and bamboo activated carbons prepared by steam activation were applied for ink wastewater treatment. Bamboo char at 800 °C was the best for the removal of color and chemical oxygen demand (COD) from ink wastewater compared to bamboo chars at 300 to 700 °C due to higher surface area and mesopore volume. Bamboo activated carbon at 600 °C (S600) was the best compared to bamboo activated carbon at 800 °C (S800), although S800 had larger surface area (1108 m(2)/g) than S600 (734 m(2)/g). S600 had higher mesopore volume (0.20 cm(3)/g) than S800 (0.16 cm(3)/g) and therefore achieved higher color and COD removal. All bamboo activated carbons showed higher color and COD removal efficiency than commercial activated carbon. In addition, S600 had the superior adsorption capacity for methylene blue (0.89 mmol/g). Therefore, bamboo is a suitable material to prepare adsorbents for removal of organic pollutants.
