Abstract
Both human health and marine life are seriously threatened by crude oil spills into bodies of water. For effective crude oil spill cleaning, we created a magnetic polystyrene (m-PS) nanocomposite. The use of magnetic nanoparticles makes crude oil absorption more environmentally friendly by making it easier to collect and recycle using an external magnetic field. To make Fe3O4 nanoparticles compatible with the hydrophobic styrene monomer used in emulsion polymerization, they were treated using a hydrophobic surface modification reaction. This alteration facilitated the grafting of polystyrene (PS) chains onto the nanoparticles, which then underwent emulsion polymerization. As an emulsifier, a light-responsive amphiphilic block copolymer containing coumarin was created via reversible addition-fragmentation chain transfer polymerization. This allowed for regulated emulsification and demulsification in response to UV stimulation. The synthesized m-PS nanocomposite demonstrated a crude oil absorption capacity of up to 2.31 times of its own weight, indicating its high efficiency for crude oil spill cleanup. The synthetic emulsifier exhibited a significantly lower critical micelle concentration compared to the commercial P105 emulsifier (0.0976 against 0.354 mg/mL, respectively), indicating higher efficiency and reduced environmental impact. For a more thorough comprehension of the reported results, we also assessed the Hofmeister effect in PS produced using commercial and synthetic emulsifiers.
期刊介绍：
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
