Development of analytical methods for determination of microplastics in the environment
AI summary Read the abstract
This Croatian thesis developed analytical methods for detecting microplastics in the environment using pyrolysis at different temperatures, finding that pyrolysis-gas chromatography conditions significantly affect the detection sensitivity for low-density polyethylene particles. The study contributes to method development for identifying and quantifying microplastics in environmental samples.
Mikroplastika, kao tvar koja onečišćuje okoliš, postala je predmetom brojnih istraživanja. Njezina identifikacija postiže se povezivanjem različitih analitičkih metoda. Polietilen niske gustoće (LDPE), kao jedan od najčešćih polimera od kojih nastaje mikroplastika, podvrgava se pirolizi na različitim temperaturama, u različitom vremenu i s različitim početnim masama uzorka, rezultirat će nastajanjem plina, ulja i čađe. Temperatura je glavni parameter koji utječe na proces pirolize. Plinskom kromatografijom povezanom s masenom spektroskopijom (GC/MS) analizira se sastav nastalog plina. Plinovi koji nastaju su alkani i alkeni (propan, 1-buten, 2-buten, ciklobutan). FTIR spektroskopijom omogućena je analiza nastalog ulja i krutog ostatka kojom je potvrđeno da se radi o ugljikovodicima.
