Abstract
Nanoplastics (NP) are the most hazardous pollutants occurring in the environment, posing significant challenges for their analysis and elimination from the environment systems. Layered double hydroxides (LDH), have found application in the NP treatment. This study investigates the surface interaction between synthesised Mg/Al LDH and carboxylated polystyrene nanoplastic (PSNP-COOH), using two experimental protocols: batch adsorption and LDH precipitation in NP presence. A novel analytical approach was developed to characterize quantitatively and qualitatively the reaction mechanism using thermal analysis, combining thermogravimetry with mass spectrometry to track mass losses and evolved volatiles during pyrolysis. PSNP-COOH distribution within the LDH crystals was evaluated using high-resolution FIB-SEM and STEM-EDS techniques. The results show that PSNP-COOH interacts with LDH via surface adsorption and physical entrapment, resulting in two PSNP-COOH populations, revealing different bonding strength and thermal behaviors. Electrostatic forces dominated in batch experiments, whereas co-precipitation favored hydrogen bonding and bridging for LDH nucleation. PSNP–COOH promoted LDH precipitation, resulting in 4.9 wt% of attached PSNP, in contrast to 1 wt% in batch experiments. The entrapped PSNP-COOH population revealed far superior thermal properties than raw PSNP-COOH, demonstrating for the first time the extending and retention effects of LDH matrices on the thermal behavior of PSNPs. This study represents the first thermal study of LDH–NP mixtures and provides a new methodological approaches for studying mineral–plastic systems. The findings also offer insights into the thermal behavior of NP–mineral mixtures, with implications for plastic pyrolysis as a strategy to remove MP and NP from wastewater and sewage sludge.
