Characterisation of microplastics is key for reliable data interpretation

Polyoxometalate nanocluster-infused triple IPN hydrogels for excellent microplastic removal from contaminated water: detection, photodegradation, and upcycling

“…50 In contrast, the XRD patterns of PP-MPs revealed sharp peaks with a bumpy baseline, indicative of both crystalline and amorphous regions in the material. 51 These findings provide valuable insights into the structural characteristics of the hydrogel matrix and MP particles, contributing to a comprehensive understanding of their material properties.…”

Aging Microplastics Enhances the Adsorption of Pharmaceuticals in Freshwater

“…However, the FT-IR spectrum of small, virgin PP demonstrated a carbonyl functional group (C=O) peak at 1711 cm − 1 (Fig. 1) that can be associated with either oxidised particles of PP or the presence of a grafting agent as discussed by Moura et al (2023). The carbonyl peak formation cannot be observed for aged particles of PET due to the presence of an ester carbonyl intensive peak at 1712 cm − 1 which is typical of PET.…”

“…S1 and S2). Prior characterisation demonstrated a wide range of sizes for the material received (Moura et al, 2023). The particles received were sieved to standardise the size range of the particles using a shaker (AS200 Control Vibratory Sieve Shaker, RETSCH) at 1.5 mm amplitude for 10 min.…”

Identification and characterization of extracted microplastics from agricultural soil near industrial area: FTIR and X‐ray diffraction method

“…Exhibit 6 shows the peak intensity and crystalline percent of different types of polymer. PET is very poor crystalline and shows broad peak and its maximum peak intensity falls in 2Θ of 25.7 and broad peaks in PS described poor crystalline in nature (Liu et al, 2019;Moura et al, 2023;Ezeonu et al, 2019).…”
