Two types of water (tap water and wastewater) and two loadings were applied throughout the planting period based on the field capacity (FC 100 and 150%). The overall dry matter yield was compared between the soils and treatments. Under wastewater irrigation, among the four species grown in the CI soil, P. purpureum (171 g) and H. annuus (151 g) showed high biomass yields, followed by S. alba (115 g) and M. sativa (31 g). The plants grown under tap water showed about 70% lower yields compared to the abattoir wastewater irrigation (AWW). Similar trends in the biomass yields were observed for CNI and CTRL soils under the two water treatments, with the biomass yields in the following order CI > CNI > CTRL soils. The results confirm the beneficial effects of AWW at the greenhouse level. However, a proper cropping pattern and wastewater irrigation management plan is essential to utilise the nutrients available in the wastewater-irrigated land treatment sites. The increase in fertility is evident from the effects of wastewater on biomass growth and also the abundance of nutrients accumulated in plants. A mass balance calculation on the applied, residual and the plant-accumulated nutrients over a few cropping periods will help us in understanding the nutrient cycling processes involved in the abattoir-irrigated land treatment sites, which will serve as an effective tool for the environmental management.]]> Wed 11 Apr 2018 12:50:36 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:21035 Wed 11 Apr 2018 11:06:12 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:50383 Tue 31 Oct 2023 08:53:22 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:54553 Tue 27 Feb 2024 20:46:24 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:2928 Tue 24 Sep 2024 11:03:03 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:39466 ® 2HT-75 (IBA) and further tailored with palmitic acid (IBAP) in order to prepare effective adsorbents. They were used for the removal of perfluorooctane sulfonate (PFOS), phenanthrene (PHE) and copper ions (Cu²⁺) both in single (S) and binary (B) contaminant conditions in simulated and real wastewater. The IB showed a large affinity for Cu²⁺ in both single (q_max: 43.43 mg/L) and binary (q_max: 43.95 mg/L) systems. Adsorption of PFOS and PHE was dramatically enhanced by the functionalized clays IBA (K_{F (PFOS)}: 11.1 and K_{F (PHE)}: 9.65 mg ^(1-n) Lⁿ g⁻¹) and IBAP (K_{F (PFOS)}): 10.2 and K_{F (PHE)}: 16.68 mg ^(1-n) Lⁿ g⁻¹). The co-occurrence of PFOS or PHE with Cu²⁺ enhanced their adsorption onto clays indicating that Cu²⁺ can form bridges between clays and PFOS or PHE in different mechanism to increase adsorption of PFOS or PHE in binary solutions. The surface-tailored organoclay IBAP showed great potential for the complete removal of PFOS, PHE and 86.6% of Cu²⁺ from real wastewater, which is usually considered challenging.]]> Tue 09 Aug 2022 14:29:54 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:38079 Tue 03 Aug 2021 15:12:30 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:55832 Thu 27 Jun 2024 12:21:19 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:47297 Thu 27 Jul 2023 11:25:51 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:29605 week 4 > week 3 > week 2. On the other hand, under the 50 % FC loading rate treatments, the highest N₂O emission was recorded in the first few weeks and in the following order: week 1 > week 2 > week 3 > week > 4. Since N₂O is a greenhouse gas with high global warming potential, its emission from wastewater irrigation is likely to impact global climate change. Therefore, it is important to examine the effects of abattoir wastewater irrigation on soil for N₂O emission potential.]]> Thu 21 Oct 2021 12:53:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:39937 Thu 14 Jul 2022 12:01:53 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:7702 Sat 24 Mar 2018 10:47:55 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:31436 6 mD and hydraulic conductivity of 1.5 cm/s. To further enhance the adsorption performance, the granules were later modified by surfactant hexadecyltrimethylammonium bromide (HDTMA) and tested for its adsorption capacity for removing toxic antifouling agent tributyltin (TBT) at high flow rate. It was found that cationic HDTMA modification enhanced the TBT adsorption capacity by 20%. This new granulation method allows the mass production of porous organo clay granules while the porous granular clay is also a good substrate for coating material such as nano sized zero-valent iron to further extent its application.]]> Sat 24 Mar 2018 08:43:13 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:8960 Sat 24 Mar 2018 08:37:08 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:1767 Sat 24 Mar 2018 08:27:37 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:17147 Sat 24 Mar 2018 07:55:07 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:6168 Sat 24 Mar 2018 07:44:38 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:355 Sat 24 Mar 2018 07:42:36 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:29586 Sat 24 Mar 2018 07:32:07 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:33454 Fri 30 Aug 2019 09:37:45 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:55670 Fri 14 Jun 2024 10:25:48 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:47369 Fri 13 Jan 2023 15:04:30 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:38433 3O₄), ferrihydrites, and desilicated minerals are identified in the RMSDN600 using XRD (X-ray diffraction) and XANES (X-ray absorption near-edge structure). Sorption isotherm for RMSD600 and SDN600 showed close-fitting with Langmuir and Freundlich model demonstrated monolayer and multilayer sorption of PFOS over the active sites of the adsorbents. The potential formation of micelles and hemi-micelles can occur in interparticle porous biochars as the concentration of PFOS exceeds critical hemi-micelle concentration (4.57-45.7 mg/L). The kinetic study followed Pseudo-second-order model for both adsorbents, demonstrated both physisorption and chemisorption of PFOS. The results revealed the adsorption of PFOS was governed by both hydrophobic and electrostatic interaction, with hydrophobic interaction as the dominant sorption mechanism. The higher adsorption capacity for RMSDN600 (194.6 mg/g) was recorded than that for SDN600 (178.6 mg/g) at pH 3.1 due to the abundance of protonated metal-based functional groups, and more ordered graphitic carbon structure resulting from catalytic degradation and transformation of cellulose and hemicellulose. Aromatic structure can potentially enhance PFOS sorption by non-ionic interaction. In contrast, metal-based and other oxygen-containing functional groups of adsorbents enhance adsorption capacity through electrostatic interaction and ion exchange reactions. Lower solution pH and smaller particle size of the adsorbents could also enhance sorption of PFOS from aqueous phase.]]> Fri 10 Sep 2021 15:11:32 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:54663 Fri 08 Mar 2024 10:57:44 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:54660 Fri 08 Mar 2024 10:56:33 AEDT ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:55599 Fri 07 Jun 2024 14:34:43 AEST ]]> https://nova.newcastle.edu.au/vital/access/manager/Repository/uon:31924 Fri 06 Apr 2018 10:58:10 AEST ]]>
