Analytical Methods for Determining of Total Arsenic in Orgasol 2002 (Polyamide-12) by Atomic Absorption Spectrophotometry

Abstract

This general approach ensures robust arsenic determination in challenging polymer matrices like Nylon-12, providing sensitive results for regulatory compliance or quality control. Chemical contamination is caused by human activities. In this study presents a validated analytical method for quantifying arsenic in Orgasol 2002 polymer samples using flame Atomic Absorption Spectrometry (AAS). Orgasol 2002 samples were digested by hot plate -assisted acid decomposition prior to analysis. Calibration standards were prepared in the range of 0.5–10 ppm. The method exhibited good linearity (R² > 0.9986), and satisfactory recovery 85.8%. The result of the determination of arsenic metal content in Orgasol 2002 was 0.43 mg/Kg.  Average percentage of spiked and spiked duplicates was 85.7%. Average sample results meet the requirements. The optimized procedure demonstrated that AAS provides a reliable and sensitive technique for trace arsenic determination in polymeric materials. Results indicate arsenic content in tested Orgasol 2002 batches was below regulatory limits. This method is suitable for routine quality control and compliance testing.
