“…When these samples are irradiated with X-rays, the intensity as a function of energy can be calculated over the energy range 1-20 keV at the same computing conditions. Figure 2 shows 18.86 keV corresponding to Si-k α , S-k α , Cl-k α , Fr-M β , Ca-k α , Ca k β , Ti-k α , V-k α , Fe-k α , Cu-k α , Zn-k α , As-k α , Kr-k α , Zr-k α , Nb-k α , Mo-k α , Nb-k β lines. It shows from figure that the intensity of Ti-k α for HDPE sample has higher intensity than the other plastics samples, while the intensity of As-k α , Krk α and Zr-k α have lower intensity or almost negligible intensity.…”

“…PP is about 100% in both PET and PVC plastics, which is highly hazardous if daily used. PET has great choice for various food products, mainly beverages such as mineral water, soft drink bottle and fruit juice containers [18], while applications of PVC has include wire and cable insulation, window frames, boots, food foil, medical devices, blood bags, automotive interiors, packaging, credit cards and synthetic leather [15].…”

The thermal behaviors of enzymatic hydrolysis lignin (EHL), high-density polyethylene (HDPE), and their blend (50:50 wt.%) were revealed using thermogravimetric analysis coupled with Fourier transform infrared spectroscopy (TG-FTIR). A first-order reaction model (Coats-Redfern) and non-isothermal model-free method (Ozawa-Flynn-Wall) were applied to the TG experimental data to determine the pyrolysis kinetic parameters. The results showed that H2O and CO2 were first released from the EHL due to the degradation of the weakly linked side chains. The degradation of lateral chains, the breakage of aromatic series in the EHL structure, and the β scission of HDPE led to the formation of H2O, CO2, C=O, aromatics, alkanes, and alkenes. Low intensities of H2O, CO2, alkanes, and alkenes were also observed in the final pyrolysis stage due to the degradation of lignin groups. Interactions during co-pyrolysis were observed in the pyrolysis stages of 390 to 542 °C and 563 to 790 °C. The activation energy values of EHL, HDPE, and their blend obtained by the Coats-Redfern method were 48.0 to 94.4 kJ/mol, 230.2 kJ/mol, and 42.7 to 260.1 kJ/mol, respectively. When the Ozawa-Flynn-Wall method was applied, activation energy ranges of 121.4 to 243.7 kJ/mol, 143.5 to 335.9 kJ/mol, and 74.8 to 260.9 kJ/mol for EHL, HDPE, and their blend, respectively, were observed.
