The maximum adsorption capacities of Sb(V) calculated from the Langmuir model were 161.3 and 151.5 mg/g for MOF-Y and NH2-MOF-Y, respectively. The Y-based MOFs exhibited strong water and chemical stability, it could be utilized for removal Sb(V) under wide pH range and various concentration of Sb(V). The spent adsorbents could be successfully regenerated by NaCl (5 mol/L) solution for further utilization without damaging the crystal structure of Y-based MOFs. X-ray photoelectron spectroscopy (XPS) and energy dispersive spectroscopy (EDS) results revealed that the formation of inner-sphere Y-O-Sb complex between Y-oxo-clusters and Sb(V) was the dominant adsorption mechanism, while the co-precipitation of Y3+ and Sb(V) was also partially contributed the Sb(V) adsorption. High stability together with high Sb(V) adsorption capacity and excellent recyclability endow the Y-based MOFs as promising adsorbents for Sb(V) removal from wastewater.]]> Wed 22 Mar 2023 18:38:30 AEDT ]]> Effect of electrolyte species on the adsorption of a cationic surfactant to silica: the common intersection point https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:8103 Wed 11 Apr 2018 15:10:09 AEST ]]> Two layered Bi-based borate photocatalysts MBi2B2O7 (M = Ca, Sr) for photocatalytic degradation and oxygen activation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41889 2B₂O₇ (CBBO) and SrBi₂B₂O₇ (SBBO) via solid-phase reaction. The crystal structure, microstructure and optical properties were investigated. The photocatalytic activities were studied by decomposition of tetracycline hydrochloride (TH) and evolution of reactive oxygen species (ROS) under UV light irradiation. The results revealed that CBBO and SBBO exhibit benign TH degradation activity with certain mineralization abilities. Within 4 min illumination, almost 70% and 58% of tetracycline hydrochloride was degraded by CBBO and SBBO, respectively. The quantitative capture experiment of radicals showed that the production rate of radical ^·OH and radical ^·O₂− was determined to be 1.27 × 10^-7 and 10.98 × 10^-7 mol·L^-1 min^-1 for CBBO and 1.01 × 10^-7 and 11.75 × 10^-7 mol·L^-1 min^-1 for SBBO, respectively. Density functional theory (DFT) calculation results demonstrated that CBBO has smaller effective masses of electrons and holes than SBBO, which results in higher charge separation efficiency and photocatalytic activity. This work provides two new layered bismuth-based borate photocatalysts for photocatalytic environmental applications.]]> Tue 16 Aug 2022 10:16:38 AEST ]]> Heteroaggregation with nanoparticles: effect of particle size ratio on optimum particle dose https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:658 Thu 25 Jul 2013 09:10:28 AEST ]]> Non-ionic surfactant interactions with hydrophobic nanoparticles: impact on foam stability https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:8104 Sat 24 Mar 2018 08:40:04 AEDT ]]> Effect of esterically bonded agents on the monolayer structure and foamability of nano-silica https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:6999 Sat 24 Mar 2018 08:37:48 AEDT ]]> Stability and flotation behaviour of silica in the presence of a non-polar oil and cationic surfactant https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:1278 Sat 24 Mar 2018 08:32:30 AEDT ]]> The influence of interfacial ageing and temperature on the coalescence of oil droplets in water https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:12350 Sat 24 Mar 2018 08:18:32 AEDT ]]> The formation of polyethyleneimine-trimethoxymethylsilane organic-inorganic hybrid particles https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:19606 Sat 24 Mar 2018 07:58:23 AEDT ]]> Orthokinetic heteroaggregation with nanoparticles: effect of particle size ratio on aggregate properties https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5511 Sat 24 Mar 2018 07:46:38 AEDT ]]> Influence of polymer charge on the compressive yield stress of silica aggregated with adsorbed cationic polymers https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5229 Sat 24 Mar 2018 07:44:18 AEDT ]]> The effect of ozonation on aggregation of humic substances on mica studied by atomic force microscopy https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:5396 Sat 24 Mar 2018 07:43:56 AEDT ]]> Surface foam film waves studied with high-speed linescan camera https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:385 Sat 24 Mar 2018 07:42:32 AEDT ]]> Condensation on hydrosol modified polyethylene https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:31 Sat 24 Mar 2018 07:42:18 AEDT ]]> Zeta-potentials of self-assembled surface micelles of ionic surfactants adsorbed at hydrophobic graphite surfaces https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3409 Sat 24 Mar 2018 07:21:36 AEDT ]]> Effect of sodium dodecyl sulphate and dodecanol mixtures on foam film drainage: examining influence of surface rheology and intermolecular forces https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3494 Sat 24 Mar 2018 07:20:34 AEDT ]]> On the forced drainage of foam https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3445 Sat 24 Mar 2018 07:20:33 AEDT ]]> The isoelectric points of sapphire crystals and alpha-alumina powder https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3393 Sat 24 Mar 2018 07:18:58 AEDT ]]> The rheology of concentrated suspensions of depletion-flocculated latex particles https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3385 Sat 24 Mar 2018 07:18:58 AEDT ]]> Hydrophobization of minerals by sorbitan mono oleate (Span® 80): Selectivity of a novel agglomeration process https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39748 Mon 20 Jun 2022 09:27:00 AEST ]]> DEM modelling of particle-bubble capture through extended DLVO theory https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33974 Fri 25 Jan 2019 14:41:59 AEDT ]]> Affinities of solvated rare earth cations with collectors and mineral interfaces: A density functional theory investigation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:55258 Fri 03 May 2024 15:23:06 AEST ]]>
