“…Further, the characteristic fingerprint region for polysaccharide is shown by absorbance intensity in the range 1000–1100 cm −1 . It is reported that the hydroxyl groups, both aliphatic and aromatic, present in lignin, pectin, and flavonoids are accountable for the heavy metal sorption .…”

“…It possesses functional groups like NH 2 , COOH, OH, SO 3 H on galacturonic acid units that assist in metal ion binding. CLP is similar to ion exchange resins in terms of performance; it can be reused multiple times for metal removal and are cheaply available . The reuse of CLP can solve two major environmental problems, that is, pollution caused by metal containing wastewater and problems of disposal of this agricultural waste.…”

The potential of an agro industrial waste Citrus limetta peels (CLP) for biosorption of Ni(II) ions from aqueous solution was explored in batch system in terms of equilibrium, kinetics and thermodynamics. The peels were characterized by FTIR spectroscopy, TGA analysis, and SEM. The effect of process parameters such as initial pH, metal ion concentration, biosorbent dosage and contact time on metal ion sorption was examined. The optimum values for pH and biosorbent dose for Ni(II) sorption were 6 and 2 g/L, with time for equilibrium adsorption 45 min. Application of the experimental data to several kinetic models and adsorption isotherms showed that the adsorption process follows a pseudo second order and Langmuir isotherm. The maximum adsorption capacity was found to be 27.78 mg/g. Elution efficiency was determined with different concentrations of HCl. Effect of various competing ions on sorption was also evaluated. The study was extended to metal sorption from synthetic wastewater. Results indicate that the CLP can be an effective and environmentally friendly adsorbent to detoxify Ni(II)‐polluted wastewater. The high nickel adsorption capacity of CLP suggests its utility on industrial scale. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 864–872, 2017

“…Uranium sorption from freshwater sources onto Citrus limetta peels 18 and citrus reprocessing waste 19 has been reported recently. With regard to the extraction of uranium from seawater, Chlorella dry cells and orange peels adsorb a great quantity of uranium; in contrast, some natural high polymers such as chitin, chitosan, cellulose and starch do not absorb uranium signicantly from seawater.…”

“…Unlike with the polymers, where the biofouling layer has to be removed to recover the elements of interest, this layer is functionally indistinguishable from the materials, especially if suitably encapsulated. While biomaterials has not been subject to a full scale attempt for the extraction of uranium from seawater previously, some data is available from leach and tailing mining environments, where attempts have been made to decontaminate ground or surface waters with a number of substances, or aimed at elements other than uranium (Ramamoorthy, et al, 1969 [25]; El-Sheikh, 2016 [26]; Tang, et al, 2013 [27]; Diallo, et al, 2015 [28]; Gondhalekar & Shukla, 2014 [29]; Satari & Karimi, 2018 [30]). These tests are generally based on testing the sorption isotherm of the material, most commonly in conjunction with a simulated liquid phase.…”
