Abstract

This study evaluated the coagulation process using Aluminum Sulfate (Al₂(SO₄)₃) for the removal of pristine and aged low-density polyethylene (LDPE) microplastics (MPs). The methodological procedure consisted of an experimental assay applying coagulation in specialized equipment (Jar Test) for MP removal, with turbidity analysis as a control parameter for coagulation/flocculation efficiency. Subsequently, the treated samples underwent laser granulometry to assess the Mean Diameter (Mz) parameter, evaluating the coagulant’s effect on aggregate formation. The key findings demonstrated optimal removal efficiencies for pristine and aged MPs (30, 90, and 120 days), with maximum removal rates of 96.47%, 97.85%, 99.07%, and 77.28%, respectively. This technique proved highly effective in MP removal, particularly for MPs degraded up to 90 days.
