Carboxylated Polystyrene Particles for Plastic Standards in Laser Ablation ICP-MS Trace Elements Analysis: Analytical Aspects and Environmental Relevance.

ABSTRACT: Reliable quantification of trace metals in polymers by direct solid-state analysis remains limited by the lack of suitable reference materials. In this study, we introduce a novel method for producing standardized plastic samples specifically designed for the calibration and analysis of trace metals by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Carboxylated polystyrene (PS) nanoparticles, capable of adsorbing metal ions from solution, were synthesized and evaluated. The trace metal adsorption capabilities of these PS nanoparticles were assessed with adsorption isotherms fit well with the Freundlich model. The study focused cobalt (Co²⁺), copper (Cu²⁺), and lead (Pb²⁺) The adsorption constants were found to be 0.15 for Co²⁺
