Concurrent grinding is shown to result in a significant increase in magnesite yields for non-heat activated feedstock, prepared such that fines (<20 µm particles) were excluded from the feed. We assert that concurrent grinding may be a suitable technique for the processing of feedstocks such as those containing significant proportions of forsterite and pyroxene, minerals which are unresponsive to thermal activation for use in aqueous mineral carbonation. This study also investigates the effect of different grinding media particle size on reducing the particle size distribution (PSD) of the feed. Optimum ratio of grinding media size to feed particle size, optimum grinding media and slurry concentrations, optimum time for grinding and optimum impeller designs are determined for the system under study. The quantitative effect of grinding media concentration, slurry concentration, pressure and temperature on magnesite yield has been investigated.]]> Wed 10 May 2023 14:51:12 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34898 Wed 07 Feb 2024 16:53:23 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46588 −1) was found for habitat service (30780), nutrient cycling (12626), and gas regulation (7224.81), whereas, lower ESVs were approximated for water regulation (347.81), raw material production (777.82) and waste treatment (13.57) services. Among the nine ESs evaluated, climate regulation, gas regulation, and disturbance regulation were the most important regulating services of the SBR. The combined effects of climate change and land-use dynamics on ESs are much stringent in a vulnerable region like the SBR. Most of the regulating services were closely associated with the fluctuation of land use land cover input. Thus, land management policies and land reform strategies that will encourage the conversion of productive land, especially the highly productive mangrove forest, for the development or any other financial benefits, would disturb the ideal human-nature balance of this ecosystem. The outcomes of this study also provide an important reference to the land administrators, researchers, and decision-makers to comprehend the expected social-ecological juxtaposition in a protected natural reserve region like the Sundarbans.]]> Wed 07 Feb 2024 16:41:15 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39084 Wed 07 Feb 2024 16:38:56 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52181 Wed 07 Feb 2024 15:21:07 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50262 16.25 LMH).

Application of the 2% (w/w) FA-BC also significantly reduced the leaching of total P (81.3%) from the soil column, while maintained an appropriate level of bioavailable P in the soil for sustaining plant growth. The chemical sequestration test and in-situ P k-edge XANES analyses of the FA-BC incubated soils revealed that the labile Ca-P fractions were transformed into stabilized Fe/Al-P complexes. The increased soil pH, a higher degree of soil P saturation, and intensive interaction between P and Fe/Al (hydr)oxides also contributed to the superior ability of the FA-BC amended soils towards P retention.

The adsorption capacity of Cu-EDDS (32-38%), Pb-EDTA (~20%), and Zn-EDTA (~0%) complexes was limited. However, the co-existence of FWC and EDDS increased the mobilization of Cu and Zn, while the co-existence of FWC and EDTA reduced the available amounts of Cu and Pb in solution. Metal speciation calculation showed that nearly all extracted Cu, Zn, and Pb were complexed with chelants in the solution, while notable amount of dissolved Fe (but not Al and Ca) was associated with dissolved organic matter. In this study, FWC can be useful for minimizing the unintended leaching of Cu- and Pb-EDTA complexes in EDTA-enhanced phytoremediation, yet it might be less suitable for the case of EDDS.

Subsequent reduction of total dissolved solids and suspended solids in the range of 78-82% and 76-77% in LSP & RSP was also observed. Mineralogical analysis using X-ray diffraction technique along with standards (lime, calcite, lime & calcite mix) confirms the production of calcite. Statistical analysis showed a P value < 0.05 indicating a higher degree of correlation (R₂ > 0.95) among the process conditions and variables using response surface methodology and was further validated using artificial neural networking.

Energy-dispersive X-ray spectroscopy (EDS) elemental mapping demonstrated that MB has a co-distribution with silicon, aluminium, and alginate carbon phase but is limited with iron and nickel, indicating HNTs and alginate polymer performed as sorption sites, whereas NiZnFe4O4 performed as a catalyst. The presence (post-sorption) and absence (pre-sorption) of inorganic, total carbon or total organic carbon content at different solution pH, contact time, and initial concentration of MB demonstrated that the adsorbent act as a catalyst as well for degradation of MB. NiZnFe4O4-HNT@alg triggers efficient removal of MB with the assist of adsorption and catalytic degradation at broad solution pH.

Their formation was validated using a number of optical spectroscopic and electron microscopic techniques. The particle size of green ZnO NPs averaged as 35 nm which was far smaller than that prepared by conventional chemical methods for comparison purpose (e.g., 48 nm). Although both types of ZnO NPs were spherical with high crystallinity, the former is likely to better reflect the strong reducing and capping capability of the leaf extract. The suitable concentrations of ZnO NPs for seedling emergence and germination of wheat (Triticum aestivum L.) were then explored at varying NP levels (0, 15, 62, 125, 250, and 500 mg/L). Accordingly, the ones treated with green ZnO NPs grew better than the control seeds. Moreover, the wheat seed samples treated with a moderate amount (e.g., 62 mg/L) of green ZnO NPs showed most significant enhancement (P < 0.005) in their root and shoot length relative to other concentration levels or to the chemically synthesized ones (e.g., by 50% and 105%, respectively).
