Abstract

Current methodologies for microplastic polymer identification such as Fourier-transform infrared and differential scanning calorimetry are neither cost-efficient nor practical in fieldwork. Density analysis is an inexpensive and readily transportable alternative method. However, current density analysis methods use many different hazardous solutions to carry out separation and identification of plastics. We demonstrate the use of water, sucrose, and ethanol solutions for the density analysis of microplastics. The method developed was able to successfully distinguish between and identify 8 polymers commonly found in microplastic pollution.
