Interestingly, in Cd2+–Cu2+ system the earlier adsorbed Cd2+ could be completely replaced by Cu2+ from the solution. Different competitive adsorption ability of those heavy metal were due to the characteristics of heavy metal and resultant affinity of the adsorption sites on E–CMBC. The adsorption mechanism indicated that chemical adsorption played a dominating role. Therefore, E–CMBC could be a potential adsorbent for wastewater treatment.]]> Thu 28 Jul 2022 15:24:26 AEST ]]> Ultrasound-assisted extraction of GAC peel: An optimization of extraction conditions for recovering carotenoids and antioxidant capacity https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41195 Momordica cochinchinensis Spreng.), which is considered as waste of Gac processing, has been found to possess high levels of carotenoids and other antioxidants. This study aimed at determining the optimal conditions of an ultrasound-assisted extraction for recovering carotenoids and antioxidant capacity from Gac peel. A response surface methodology using the Box–Behnken design was employed to investigate the impact of extraction time, temperature and ultrasonic power on the recovery of total carotenoid and antioxidant capacity. The results showed that an extraction time of 76 min, temperature of 50 °C and ultrasonic power of 250 W were the optimal conditions for the extraction. The experimental carotenoid yield and antioxidant capacity obtained under the optimal extraction conditions were validated as 269 mg/100 g DW (dry weight) and 822 µM TE (Trolox equivalent)/100 g DW, respectively. These values were not significantly different from the values predicted by the models. The HPLC analysis for carotenoid composition showed that β-carotene, lycopene and lutein were the principal carotenoids of the extract, which constitute 86% of the total carotenoid content. Based on the obtained results, the ultrasound-assisted extraction using ethyl acetate under the above optimal conditions is suggested for the simultaneous recovery of carotenoids and antioxidant capacity from Gac peel.]]> Thu 28 Jul 2022 11:12:19 AEST ]]> Highly stable and nontoxic lanthanum-treated activated palygorskite for the removal of lake water phosphorus https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39734 Thu 28 Jul 2022 08:55:29 AEST ]]> Effects of Phosphate, Red Mud, and Biochar on As, Cd, and Cu Immobilization and Enzymatic Activity in a Co-Contaminated Soil https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45403 Thu 27 Oct 2022 17:22:16 AEDT ]]> Recovery of Phenolic Compounds and Antioxidants from Coffee Pulp (Coffea canephora) Waste Using Ultrasound and Microwave-Assisted Extraction https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52211 Thu 05 Oct 2023 10:24:26 AEDT ]]> Investigation of the most suitable conditions for dehydration of Tuckeroo (Cupaniopsis anacardioides) fruits https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40415 Cupaniopsis anacardioides) is an Australian native tree, possessing high level bioactivity and antioxidant activity. To prevent deterioration of active constituents, appropriate drying practices must be determined. This study comparatively evaluates the impact of a range of drying methods including freeze-, microwave-, vacuum-, hot air- and sun-drying on the physical, phytochemical and antioxidant characteristics of Tuckeroo fruit. Experimental results showed that the five drying methods had significant impact on the physicochemical properties and antioxidant activity of the fruits. Of the drying methods assessed, freeze drying best preserved Tuckeroo activity, recording higher total phenolic content (TPC) (81.88 mg gallic acid equivalent (GAE)/g), total flavonoids (TFC) (107.71 mg catechin equivalent (CAE)/g), proanthocyanidins (TPro) (83.86 mg CAE/g) and exhibited the strongest antioxidant capacity. However, vacuum drying at 65 kPa, 100 ℃ for 5 h is recommended for drying Tuckeroo fruits for further processing in a large scale as it also retained high levels of TPC, TFC and TPro (58 mg GAE/g, 91 mg CAE/g and 74 mg CAE/g, respectively).]]> Mon 11 Jul 2022 14:44:41 AEST ]]> CFD modeling of flame jump across air gap between evasé and capture duct for ventilation air methane abatement https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42799 Mon 05 Sep 2022 09:08:32 AEST ]]> Abatement of Greenhouse Gas Emissions from Ventilation Air Methane (VAM) Using Ionic Liquids: A Review of Experimental Methods and Modelling Approaches https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51081 Fri 18 Aug 2023 09:32:00 AEST ]]> Impact of Various Essential Oils and Plant Extracts on the Characterization of the Composite Seaweed Hydrocolloid and Gac Pulp (Momordica cochinchinensis) Edible Film https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48911 Fri 14 Apr 2023 18:33:01 AEST ]]>
