Birnessite exhibited great affinity for As and drastically reduced As extractability by more than 90% in all single extractions. The results revealed that HDPC-M, HDPB-Z, La-Euchar, birnessite, and goethite are promising immobilizing agents for in situ stabilization of As in terrestrial environments.]]> Wed 18 Oct 2023 13:47:13 AEDT ]]> Effects of thermal treatments on the characterisation and utilisation of red mud with sawdust additive https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24638 Wed 11 Apr 2018 14:14:24 AEST ]]> Toward In Situ Sequestration of Multicomponent PFAS Using Injectable Adsorbent Suspensions https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54621 Wed 06 Mar 2024 10:53:01 AEDT ]]> Staphylococcus edaphicus KCB02A11 incorporated with natural adsorbents: first report on its tolerance and removal of hexavalent chromium [Cr(VI)] https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52822 Mon 30 Oct 2023 08:43:15 AEDT ]]> Biodegradable composite adsorbent of modified cellulose and chitosan to remove heavy metal ions from aqueous solution https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43431 2SO4 to have better adsorption properties. On the contrary, modification of chitosan was carried out by acetaldehyde solution and acetic acid. Composite adsorbent was obtained as a mixture, comprising of modified cellulose and chitosan in a specific proportion (2g:1g). The surface characteristics of treated cellulose, chitosan and composite sample were evaluated by FTIR and SEM analysis. In addition, batch adsorption experiments were carried out to measure the influences of pH of the solution, adsorbent dosage and the initial concentration of metal ions. The maximum removal efficiency of Cr, Pb and Cd by composites was 56, 85 and 94%, respectively, at pH 4 when the metal concentration and adsorbent dosage were 60 ppm and 1.0 g L-1. The maximum adsorption of Cr, Pb and Cd by composites was 55, 80 and 91 mg g-1, respectively, at pH 4 when the metal concentration and adsorbent dosage were 120 ppm and 1.0 g L-1.]]> Mon 19 Sep 2022 10:57:46 AEST ]]> A facile synthesis of hematite nanorods from rice starch and their application to Pb(II) ions removal https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35269 Mon 08 Jul 2019 11:02:20 AEST ]]> Synthesis, characterization and adsorptive performances of functionalized clay minerals and red mud for aqueous arsenic removal https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54852 Fri 15 Mar 2024 17:15:42 AEDT ]]> The effects of chitosan composites on the immobilization of chromium in soil and marigold (Calendula officinalis) growth https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45759 Fri 04 Nov 2022 11:02:02 AEDT ]]>
