The effects of different operating parameters such as adsorbent dose, initial fluoride concentration, pH of the solution and interfering ions (usually present in groundwater) were studied with a view to understand the adsorption behavior of the material under various conditions. A thermodynamic study shows that the adsorption of fluoride by alkoxide origin alumina is an exothermic and spontaneous process. The kinetic results showed that the fluoride sorption follows pseudo-second-order kinetics. The applicability of adsorbent in the field is also tested through column breakthrough studies. It has been observed that with an increase in the flow rate and initial fluoride concentration, the breakthrough curve becomes sharper and the breakthrough time and adsorbed fluoride ion concentration decrease. The breakthrough curve also becomes steeper as the bed height increases. The alkoxide origin alumina based adsorbent media can be used directly for field applications since it is also commercially available in granular form. (C) 2010 Elsevier B.V.

This paper critically reviews the reported work and investigates various FPW-pollutant systems. The study includes statistics of FPW generation, modification, characterization, adsorption ability, recovery/regeneration, and modeling (isotherms, kinetics, and thermodynamics) of batch adsorption. It is found that orange and banana peels are the most extensively studied adsorbents, whereas Pb2+ and methylene blue are the most efficiently removed pollutants, the Langmuir and Freundlich adsorption isotherms provide the best fit in most of the cases, and in general, pseudo-second-order kinetics is followed. There are very limited column studies and no report on commercial plant. Though the reproducibility of the results is poor, FPW has a great potential in the wastewater treatment due to its abundant and cheap availability. FPW can be used for removal of heavy metals and dyes; however, removal of organic and gaseous impurities needs further investigation.</p>10aadsorbent10aAdsorption10afruit peel waste10aorganic and inorganic pollutants10awastewater1 aPathak, Pranav, D.1 aMandavgane, Sachin, A.1 aKulkarni, Bhaskar, D.  uhttps://library.ncl.res.in/content/fruit-peel-waste-novel-low-cost-bio-adsorbent-001441nas a2200229   4500008004100000022001400041245012400055210006900179260008600248300001600334490000700350520055900357653001500916653001600931653001800947653001900965653002500984100002301009700002701032700002601059856012601085       2016                        eng d  a1944-399400aUtilization of banana peel for the removal of benzoic and salicylic acid from aqueous solutions and its potential reuse0 aUtilization of banana peel for the removal of benzoic and salicy  a530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USAbTAYLOR & FRANCIS INCcJUN  a12717-127290 v573 a<p>We report on the adsorptive removal of benzoic acid (BA) and salicylic acid (SA) using banana peel (BP), an abundantly available agricultural waste material, for the first time. BP was characterized by proximate analysis, FT-IR, scanning electron microscopy, BET surface area, and XRF. The number of basic sites on BP (4.9mmolg(-1)) is relatively more than acidic sites (0.75mmolg(-1)). The Langmuir uptake capacity values obtained are 6.62mgg(-1) for BA and 9.80mgg(-1) for SA. A mechanism for binding acid molecule to the BP surface is proposed.</p>10aAdsorption10aBanana peel10aBenzoic acids10aSalicylic acid10aWastewater treatment1 aPathak, Pranav, D.1 aMandavgane, Sachin, A.1 aKulkarni, Bhaskar, D.  uhttps://library.ncl.res.in/content/utilization-banana-peel-removal-benzoic-and-salicylic-acid-aqueous-solutions-and-its-0
