“…Sommer et al described the use of LIBS to study the weathering-induced oxidation of polystyrene; some of which had been treated with the anti-oxidant Irgafos. 113 The LIBS was used to examine the spectral features of oxidation, i.e. monitor the species CN, C 2 , H and O; with O being monitored at 777.3 nm.…”

Micro (nano) plastics, MNPLs, have become emerging particulate human-made pollutants, and quickly become the fields of increasing concern of the public. Due to the lack of analytical technology with sufficient sensitivity and selectivity, it is difficult to fully detect and determine the characteristics of MNPLs in the environment and biological matrix. Atomic spectrometry has many advantages, such as low detection limit and high sensitivity, and shows great potential in the analysis of MNPLs. However, there is a lack of systematic summary in this field at present in order to give full play to its advantages in the analysis of plastics. In this review, the whole process of analyzing MNPLs in complex matrix based on various atomic spectroscopy techniques have been discussed, including sample labeled, treatment, purification, and detection. Furthermore, the application of atomic spectrometry in tracing the source of MNPLs in the environment, in situ identification and classification, analysis surface morphology and functional groups changes during aging process, assessments of environmental ecological risk assessment and toxicological effects were addressed aiming to improve our understanding on the environmental fate and transport of the fragments. Finally, future outlooks and research directions have been recommended based on the existing research gaps in the area.

“…Banaee et al [34] studied the classification of recyclable polymers using discriminant function analysis (DFA) coupled with LIBS data. Recently, Sommer et al [35] studied the effect on the sample's surface and its depth profile for the weathering-induced oxidation of polystyrene target samples at different weathering times using the LIBS methodical tool. More recently, Nie et al [36] analyzed six various colored plastics such as POM, PP, ABS, PVC, PE, and PA using LIBS blended with (NCA) and support vector machine (SVM) statistical analysis.…”

The potential of using laser-induced breakdown spectroscopy (LIBS) in combination with various other spectroscopic and statistical methods was assessed for characterizing pure and MgO-doped nylon (6/6) organic polymer samples. The pure samples, obtained through a polycondensation chemical technique, were artificially doped with MgO prior to analysis for comparative purposes. These artificially doped samples served as crucial reference materials for comparative analysis and reference purposes. The LIBS studies were performed under local thermodynamic equilibrium (LTE) and optically thin plasma conditions. To assess the structural crystallinity of the nylon (6/6) polymer samples, X-ray diffraction (XRD) analysis, and Fourier transform infrared (FTIR) spectroscopy were employed to detect functional groups such as N-H, C-H, and C-N in the adsorbent polyamide nylon sample. Additionally, diffuse reflectance spectroscopy (DRS) analysis was conducted to investigate the effects of doping and temperature on the band gap and material reflectance across different sample temperatures. Chemical compositional analysis was performed using X-ray photoelectron spectroscopy (XPS) with the carbon C1s peak at 248.8 eV serving as a reference for spectrum calibration, along with energy-dispersive X-ray (EDX) analysis, which demonstrated good agreement between the techniques. To validate the different methodologies, the results obtained from CF-LIBS and EDX were compared with those from the standard inductively coupled plasma mass spectrometry (ICP-MS) technique. Finally, for classification analysis, principal component analysis (PCA) was applied to the LIBS spectral data at different sample temperatures (25 °C, 125 °C, 225 °C, and 325 °C). The analyses demonstrated that the combination of LIBS with PCA, along with other methods, presents a robust technique for polymer characterization.
