“…K F is a Freundlich constant that shows adsorption capacity on heterogeneous sites with non-uniform distribution of energy level and n value shows the intensity between adsorbate and adsorbent ( Table 6). The values of n prove that the adsorption of fluoride ions onto BPD-1, BPD-2 and BPD-3 are favourable as the magnitude lies between 1 and 10 ( Achak et al 2009). …”

“…Initially, there were large number of vacant active binding sites in these three adsorbents (BPD-1, BPD-2 and BPD-3) and consequently large amounts of fluoride ions were bound rapidly onto the adsorbent. The binding site shortly became limited and the remaining vacant surface sites could not be occupied due to the formation of repulsive forces between the adsorbate on the solid surface and the liquid phase (Srivastava et al 2006;Achak et al 2009). Besides, the mesopores are saturated at the initial stage of adsorption where the fluoride ions are adsorbed.…”

“…However, pseudo-first-order and intraparticle diffusion plots have poor coefficient of correlation (Table 7). The adsorption mechanism depends on the physical and chemical characteristics of adsorbent and adsorbate, pH of medium, temperature, contact time and aids and mass transport process (Achak et al 2009). The data were fitted with different kinetics equation, namely pseudo-first-order, pseudo-second-order and intraparticle diffusion kinetics models.…”

The present work highlighted the effective application of banana peel dust (BPD) for removal of fluoride (F -) from aqueous solution. The effects of operating parameters such as pH, initial concentration, adsorbent dose, contact time, agitation speed and temperature were analysed using response surface methodology. The significance of independent variables and their interactions were tested by the analysis of variance and t test statistics. Experimental results revealed that BPD has higher Fadsorption capacity (17.43, 26.31 and 39.5 mg/g). Fluoride adsorption kinetics followed pseudo-second-order model with high correlation of coefficient value (0.998). On the other hand, thermodynamic data suggest that adsorption is favoured at lower temperature, exothermic in nature and enthalpy driven. The adsorbents were characterised through scanning electron microscope, Fourier transform infrared spectroscopy and point of zero charges (pH ZPC ) ranges from pH 6.2-8.2. Finally, error analysis clearly demonstrates that all three adsorbents are well fitted with Langmuir isotherm compared to the other isotherm models. The reusable properties of the material support further development for commercial application purpose.

“…Maximum absorption ability of banana husks from Langmuir isotherm indicated that 1g of banana husks can adsorb 5.71 mg of cadmium and 2.18 mg of lead. Untreated banana peels (UTBPs), alkali-hydrolyzed banana peels (AlBPs), acid-hydrolyzed banana peels (AcBPs), and bleached banana peels (BBPs) were used as adsorbents separately for the elimination of Cr(VI) and Mn(II) from aqueous solution during batch experiments [64]. The maximum elimination capacities for Cr(VI) were UTBP (45%), AlBP (87%), AcBP, (67%) and BBP (40%).…”

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.

“…The major advantages of biosorption over other conventional treatment methods include low cost, high efficiency, minimization of chemical and biological sludge, and regeneration of biosorbent by desorption techniques and possibility of metal recovery [13]. In recent years, certain raw waste products from agricultural produce, like cocoa shell [14], rice husk, [15], olivestone [16], garlic peel [17], sawdust [18], Brazilian pine-fruit shell [19] banana peel [20], Carica papaya (pawpaw) seed [21], Anabaena and Vetiveria [22] and date tree leaves [23], have been tested for removal of metals from effluents. The utilization of these raw plant materials as biosorbents has been limited due to the leaching of organic compounds such as, cellulose lignin, pectin and lignocellulose into solution.…”

The removal of Cr (VI) ions increased with increase in biosorbent concentration with the optimal adsorbent dosage at 4.0 mg/L. The increase in initial Cr (VI) ion concentration led to an increase in the percentage removal of Cr (VI). The adsorption data fitted well with the Freundlich isotherm model with
