For accurate and reliable analysis of microplastics (MPs) in wastewater (WW), it is imperative to comprehend the significance pre-treating WW before analysis. The suspended solids (SS) matrix tend adhere MPs during filtration, which interferes with detection MPs. In this regard, present study aims develop optimize a pretreatment method improve extraction efficiency from by reducing SS. A combination Fenton reaction ultrasonication, ferro-sonication (Fe-UlS), was proposed digest eliminate SS WW. This hybrid pretreatment, Fe-UlS, optimized for ultrasonication amplitude, treatment time, hydrogen peroxide dose using response surface methodology (RSM) Box-Behnken design, achieving desirability 0.984. optimum conditions such as (1:1) reagent ratio (0.05 M FeSO4: 30 % H2O2), amplitude (31 %), total process time (30 min) were found be statistically significant (p < 0.05). developed then employed spiked polyethylene (PE), polypropylene (PP) terephthalate (PET) real efficient removing 83 TSS primary influent min at temperature 45 °C. Also, did not affect physio-chemical characteristics MPs; however, thermal PE PP showed decrease melting temperature, proven paired t-test Further, non-targeted liquid chromatography-mass spectrometry (LC-MS) proved that Fe-UlS stable process, cause any leaching under conditions. Finally, Laser Direct-Infrared Imaging (LD-IR) conducted validate approach MP About 3434 detected 100 mL influent, within size range 9 500 μm. only streamlines sample processing but also reduces required concentration yielding results monitoring
