Palm shell powder (PSP) and acid treated palm shell powder (APSP) provide an attractive approach for the removal of Cu(II) from aqueous solutions and further use of the copper loaded adsorbents as catalysts. PSP was charred with sulfuric acid (H2SO4) to oxidize ligno-cellulosic groups present in PSP, resulted in acid treated palm shell powder (APSP). Structure property relationship was explored with the help of sophisticated spectroscopic tools (¹³C nuclear magnetic resonance (¹³C NMR), X-Ray photoelectron spectroscopy (XPS), X-Ray diffraction (XRD) and Fourier-transform infrared (FTIR) spectroscopy). Pretreatment lead to conversion of ligno-cellulosic content to more valuable and easily process-able polysaccharide content.APSP and PSP displayed a maximum adsorption capacity of 125 and 36 mg/g respectively for copper. Copper adsorption was found to be more in APSP due to presence of COOH groups which rendered the surface more hydrophilic and amenable to enhanced Cu²⁺ sorption. Furthermore the adsorbents loaded with copper could be used as catalysts for oxidation of styrene. The developed adsorbents promise advantages such as low cost, high adsorption capacity, environmental friendliness as well as zero sludge. </style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">1.125</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bhatt, Rahul</style></author><author><style face="normal" font="default" size="100%">Kushwaha, Shilpi</style></author><author><style face="normal" font="default" size="100%">Bojja, Sreedhar</style></author><author><style face="normal" font="default" size="100%">Padmaja, P.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%"> Chitosan-thiobarbituric acid: a superadsorbent for mercury</style></title><secondary-title><style face="normal" font="default" size="100%">ACS Omega</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year><pub-dates><date><style  face="normal" font="default" size="100%">OCT</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">3</style></volume><pages><style face="normal" font="default" size="100%"> 13183-13194</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In the present investigation, chitosan (CH) as supramolecularly cross-linked with thiobarbituric acid to form CT. CT was well characterized by UV, scanning electron microscopy-energy-dispersive X-ray analysis, Fourier trans form infrared, NMR, differential scanning calorimetry, thermogravimetric analysis, and X-ray difTraction analyses, and its adsorption potential for elemental mercury (Hg-0), inorganic mercury (Hg2+), and methyl mercury (CH3Hg+) was investigated. Adsorption experiments were conducted to optimize the parameters for removal of the mercury species under study, and the data were analyzed using Langmuir, Freundlich, an Temkin adsorption isotherm models. CT was found to have high adsorption capacities of 1357.69, 2504.86, and 2475.38 rng/g for Hg-0, Hg2+, and CH3Hg+, respectively. The adsorbent CT could be reused up elemental mercury using 0.01 N thiourea, inorganic mercury using 0.01 N perchloric acid, and methyl to three cycles by eluting mercury with 0.2 N NaCl.</style></abstract><issue><style face="normal" font="default" size="100%">10</style></issue><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">0.75</style></custom4></record></records></xml>
