Nanoplastics Identification in Complex Environmental Matrices: Strategies for Polystyrene and Polypropylene

نویسندگان

چکیده

Identification of nanoplastics in complex environmental matrices remains a challenge. Despite the increase studies, there is lack studies dedicated to detection, partially explained by their carbon-based structure, wide variety composition, and low concentrations compared natural organic matter. Here, pyrolysis coupled GCMS instrumental setup provided relevant analytical response for polypropylene polystyrene nanoplastic suspensions. Specific markers indicative fragment ions were selected validated. Possible interferences with explored spiking various matter suspensions (i.e., algae, soil matter, humic acid) analyzing an suspension nanoplastics. While rapid identification was validated, require preliminary treatment. The strategies presented herein open new possibilities detection/identification such as soil, dust, biota.

Polypropylene /Polystyrene in situ nano reinforced blends fiber: Morphology and properties

Polypropylene / polystyrene blends containing montmorillonite (MMT) were prepared using a twin screw extruder followed by fiber spinning. The melt intercalation of PP and PS alloys was carried out in the presence of a compatibilizer such as maleic anhydride-g-polypropylene (MPP). The crystallization morphology, thermal behaviors and mechanical properties of polypropylene/polystyrene (PP/PS) nan...

passivity in waiting for godot and endgame: a psychoanalytic reading

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
