Abstract:

Micro Fourier?transform infrared spectroscopy (micro?FTIR) was used to analyze and identify microplastics with different particle sizes and different compositions. These microplastics include the plastic, fiber or rubber fragments with particle size less than 5 mm. The advantages and disadvantages of three measurement modes including reflection, transmission and attenuated total reflection and their scanning technologies in the identification and analysis of microplastics were systematically described. Based on the attenuated total reflection technique of micro?FTIR, the microplastic obtained from the Beijing landscape water were analyzed and identified. The results indicated that this method was simple, accurate and reliable.

Key words: microplastics, micro?Fourier transform infrared spectroscopy, reflection, transmission, attenuated total reflection
