“…For PP, the broad adsorption peak at 3288.0 cm -1 corresponds to the O-H stretching vibrations of tannin, pectin and cellulose, thus showing the presence of ''free'' hydroxyl groups on the adsorbent surface. The peak observed at 2936.2 cm -1 can be attributed to the C-H stretching vibrations of methyl and methylene (Feng et al 2009). The peaks observed at 1724.4 cm -1 can be attributed to the carbonyl (C=O) stretching vibration of free carboxyl groups of catechin, catechol and gallic acid (Kim et al 2007).…”

“…It is shown that the Pt(IV) adsorption on GPP is strengthened by increasing temperature below 343 K. Further increasing the temperature has less effect on the adsorption efficiency. This is because that high temperature enhances adsorption, (Feng et al 2009;Cox et al 2005). However, temperature has a negative effect on the adsorption when using PP, which may be attributed to increased solubility of PP which consequently weakens the Pt(IV) adsorption by PP as increasing the temperature (Duan et al 2007).…”

A glycine-modified persimmon powder was used as biosorbent for platinum adsorption in aqueous solution. The combined effects of modifying agent amount, modifying time and temperature on Pt(IV) adsorption by persimmon biosorbent were investigated, from which the optimum modification conditions with modifying agent amount of 50 %, temperature of 333 K and contact time of 4.0 h were determined. The influences of solution initial pH, solid-to-liquid ratio, contact time, temperature and initial concentration on the Pt(IV) adsorption were studied systematically by batch experiments. The optimum modification conditions were determined as follows: chemical reagent amount of 50 %, temperature of 333 K and contact time of 4.0 h. From the adsorption kinetic analysis, it was found that the adsorption kinetics of glycine-modified persimmon powder followed a pseudo-second-order kinetic model. The adsorption isotherms of the crude persimmon powder and glycine-modified persimmon powder were analyzed with the BET-type adsorption isotherm. The adsorption mechanism of Pt(IV) on the glycine-modified persimmon was considered to be adsorption-reduction mechanism. The results achieved from this study indicated that the novel persimmon adsorbent could be applied to recover trace Pt(IV) ions from a concentrated chloride solution.

“…The uptake rate of cadmium was 94% with 0.15 mol/L HCl solution. The preparation of chemically modified orange peel cellulose adsorbents and its biosorption behaviors of Co(II), Ni(II), Zn(II) and Cd(II) have been examined [37]. The elemental analysis of raw orange husk showed that it is composed of 42.2% carbon, 5.4% hydrogen, 51.4% oxygen and 1.0% nitrogen.…”

Towards the future of green, sustainable and renewable products the suggestion of using the agriculture biomass in the coming decades got increased. Biomass material is one of the important sources of alternative material for the production of biocomposite products. An increasing global awareness about environmental issues is acting as the driving force behind the utilization of biomass material as valuable products. Bio-waste materials (agricultural waste) have been recognized as an ecological burden for the society they stimulated new gateways for the production of renewable, low cost and sustainable adsorbents for water treatment applications. In the area of water purification, nanotechnology offers the possibility of an efficient removal of pollutants and bacteria. Adsorption has proved that it is the best process of water treatment technologies, because of its significant advantages. Different modification methods of waste-based adsorbents, have also been presented to highlight and discuss the key advancements on the preparation of novel adsorbents using agricultural "agro-waste". Adsorption mechanisms responsible for pollutants removal by waste-based adsorbents have also been discussed. It also focuses on the computational aspects of binding of biomolecules to nanoparticles (NPs) and some of the applications of the biosynthesized NPs as water purification. The nature acts like a large ''bio-laboratory" comprising of plants, algae, fungi, yeast, etc. which are composed of biomolecules. These naturally occurring biomolecules have been identified to play an active role in the formation of nanoparticles with distinct shapes and sizes thereby acting as a driving force for the designing of greener, safe and environmentally benign protocols for the synthesis of NPs. The biosynthesis of NPs using waste materials will help researchers not only to design safer nanomaterials but also to promote the understanding of health and safety considerations of NPs. Useful materials can be produced easily even at reasonable scale because the biomaterial based routes eliminate the need to use toxic chemicals. The aim of this review is to summarize the adsorption capacities for organic and inorganic pollutants by different bio-waste-based adsorbents.

“…Feng et al (2009) deduced that the Langmuir isotherm model gave the best fit to the equilibrium data for the adsorption of copper (II) onto chemically modified orange peel prepared from hydrolysis of the grafted copolymer, which was synthesized by interaction of methyl acrylate with cross-linking orange peel. Demirbas et al (2009) studied the adsorption Han et al (2010) found that the equilibrium data from the adsorption of copper (II) onto citric acid modified wheat straw were fitted well by both the Freundlich and Langmuir models (maximal equilibrium quantity of copper (II) from Langmuir model was 39.17 mg g -1 (20°C).…”

This paper reports the potential of chemically treated wood chips to remove copper (II) ions from aqueous solution a function of pH, adsorbent dose, initial copper (II) concentration and contact time by batch technique. The wood chips were treated with (a) boiling, (b) formaldehyde and (c) concentrated sulphuric acid and characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and energy dispersive analysis X-ray. pH 5.0 was optimum with 86.1, 88.5 and 93.9 % copper (II) removal by boiled, formaldehyde-treated and concentrated sulphuric acid-treated wood chips, respectively, for dilute solutions at 20 g L -1 adsorbent dose. The experimental data were analysed using Freundlich, Langmuir, Dubinin-Radushkevich and Temkin isotherm models. It was found that Freundlich and Langmuir models fitted better the equilibrium adsorption data and the adsorption process followed pseudo-second-order reaction kinetics. The results showed that the copper (II) is considerably adsorbed on wood chips and it could be an economical option for the removal of copper from aqueous systems.
