“…The results showed that grape bagasse could be employed as a low-cost alternative adsorbent for effl uent treatment (Farinella et al 2007 ). Low et al ( 1995 ) used nitric acid-modifi ed banana pith as an adsorbent and reported the maximum adsorption capacity of 13.46 mg g −1 for Cu…”

“…Heavy metals can also be removed by a variety of biosorbents (Diels et al 1995;Kapoor and Viraraghavan 1998;Zhang et al 1999;Bankar et al 2009). In particular, environment-friendly agro wastes have emerged as important adsorbents (Bailey et al 1999;Pino et al 2006;Farinella et al 2007;Mahvi et al 2008;Al-Masri et al 2009). Plant leaves are cost-effective and easily available.…”

Paper mulberry (Broussonetia papyrifera) leaf powder was used to remove heavy metal ions from aqueous solutions. The specific uptakes of Cu (II), Pb (II), and Cd (II) by the leaf powder were 43.40±0.2, 43.9±0.5, and 30.65±0.9 mg g −1 , respectively, when 500 mg L −1 of the metal solutions were used. The data fitted well to the Langmuir isotherm. The process followed the pseudo-second-order kinetic equation and intraparticle diffusion played an important role in the adsorption process. On the basis of the calculated thermodynamic parameters such as standard enthalpy (ΔH°), entropy (ΔS°) and free energy change (ΔG°), it was inferred that the sorption process was endothermic and spontaneous in nature. The surface properties of the leaf powder (revealed by scanning electron microscopic observations) were suitable for the metal adsorption process. Energy dispersive X-ray fluorescence analysis confirmed the sequestration of the metal ions by the leaf powder. Fourier transform infrared spectroscopy implicated that different functional groups on the leaf powder were involved in the metal adsorption process. The results obtained from this study implicated that the B. papyrifera leaf powder was a good choice as a metal adsorbent. This abundantly available natural and ecofriendly biosorbent could be effectively used to develop a technology in the future.

“…The broad peak at 3324 cm -1 is due to the presence of amine groups (N-H). The band observed at 2908 cm -1 indicates the presence of C-H stretching vibrations of methyl group [50]. The peaks found at 1727 cm 1 and 1556 cm -1 were due to primary amine group.…”

Abstract. This study aimed to use sago palm bark to formulate a new adsorbent activated carbon (AC) contains highly surface area through physicochemical method via ZnCl2 activation. Conduction of the activation process was performed at varying impregnation ratios (0.5-2.0). Thermal decomposition was determined using thermogravimetric analysis (TGA). Porosity characterizations of AC were conducted by using N2 adsorption-desorption in order to characterise properties like pore volume, surface area, and micropore volume. To detect the presence of functional groups which were found on the surface of AC, Fourier Transform Infrared Spectroscopy (FTIR) analysis was utilised. Morphology of AC was determined using scanning electron microscopy (SEM) and X-ray spectroscopy (EDX). Experimental results showed that maximum AC surface area was 1737 m 2 /g. Activation temperature was revealed to be 700 o C, with chemical impregnation ratio of zinc chloride to a precursor equal to 1.5/1.
