Rising the surfactant concentration would not enhance the defluorination, the best one was obtained at its CMC. Moreover, changing the pH of the US bath liquid by adding acid or alkaline solution inhibited the defluorination, which might be attributed to acid or base causing damage to the chemical properties or physical structure of surfactant (certified by the SEM tests). Additionally, the mechanism of enhanced PFOA defluorination was examined by electron paramagnetic resonance analysis, which proved that adding surfactant facilitated the generation of the radicals (·OH and SO4∙-), as well as the radicals’ amount increased over time during 60 min. Finally, the inhibited defluorination of adding surfactant directly to the PFOA solution was studied by the SEM analysis, the results demonstrated that adsorption and wrapping between surfactant micelles and PFOA reduced the contact between PFOA and radicals and affected the surfactant effect on the surface tension.]]> Tue 25 Jul 2023 18:05:23 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47011 Tue 13 Dec 2022 11:41:23 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55455 Mon 03 Jun 2024 08:45:49 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38320 −1) and dissolved organic matter(0–20 mg L⁻¹). The string rate of more than 100 rpm indicated the DGT will not likely be affected by flow rate in the aquatic environment. The study successfully indicates the DGT’s performance on diuron, providing a promising technique for future investigation of distribution and occurrence in the natural environment.]]> Fri 27 Aug 2021 12:02:40 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40151 5 mm) plastic residues. We have found that microplastics can be generated by simple tasks in our daily lives such as by scissoring with scissors, tearing with hands, cutting with knives or twisting manually, to open plastics containers/bags/tapes/caps. These processes can generate about 0.46–250 microplastic/cm. This amount is dependent on the conditions such as stiffness, thickness, anisotropy, the density of plastic materials and the size of microplastics. This finding sends an important warning, that we must be careful when opening plastic packaging, if we are concerned about microplastics and care about reducing microplastics contamination.]]> Fri 22 Jul 2022 13:55:19 AEST ]]>
