Results indicated 100% of phenanthrene was removed, total COD removed increased to 81.5%, 77.2% and 68.7% using N₂, O₂ and air–Fe NPs, respectively. In addition, Fe NPs were confirmed by scanning electron microscopy (SEM) and X-ray energy-dispersive spectroscopy (EDS). Finally, the degraded metabolites were identified by GC–MS to understand the degradation pathway]]> Sat 24 Mar 2018 07:37:59 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27744 Pseudomonas sp. strain were also carried out. Results showed that after 1 and 25 d, HPCD at pH 7 extracted significantly more View the MathML source14C-phenanthrene (p<0.05)(p<0.05) from BC-amended soils than the other two solutions (un-buffered and pH 8), while HPCD at pH 8 extracted statistically similar (p>0.05)(p>0.05) amounts of phenanthrene compared to the un-buffered solution. At 50 d, HPCD at pH 8 generally extracted more ¹⁴C-phenanthrene from all treatments. It was proposed that higher pH promoted the dissolution of soil organic matter (SOM), leading to a greater solubility of phenanthrene in the solvent phase and enhancing the extractive capability of HPCD solutions. Although correlations between extractability and biodegradability of ¹⁴C-phenanthrene in BC-amended soils were poor, increasing pH was demonstrated a viable approach to enhancing HPCD extractive capability for the ¹⁴C-PAH from soil with BC.]]> Sat 24 Mar 2018 07:27:45 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27309 Mon 23 Sep 2019 14:19:56 AEST ]]>
