N,N-dimethylformamide dialkylacetals are very powerful derivatization reagents. The most known member of this group is N,N-dimethylformamide dimethylacetal or shortly DMF-DMA. We tried to use this compound to derivatize perfluorooctanoic acid (PFOA) and form an ester. However, our research showed...

Investigations on the influence of short-term microplastics exposure on soluble micropollutants in municipal wastewater treatment plants
Michael Sturm, Dennis Schober, Dr. Katrin Schuhen, Wasser 3.0
The water entering sewage treatment plants increasingly poses challenges for operators. More and more often, there is a growing amount of microplastic in rainwater and wastewater for example due to fibers in synthetic clothing such as fleece jackets, tire abrasion or due to the input from industr...

Determination of particles produced during boiling in differenz plastic and glas kettles via comparative dynamic image analysis using FlowCam®

Sven Kluczka, Anasysta e.K.
In many everyday products containing plastics, tiny plastic particles are generated by mechanical, thermal or other influences and are released into the environment by various transport routes. These particles not only have a long lifecycle, but can also only be degraded very slowly in the ecosys...
