Evaluating the effectiveness of H2O2 filter cleaning for microplastic analysis
Summary
Researchers evaluated the effectiveness of hydrogen peroxide treatment at three concentrations for cleaning filters bearing dark brown tissue residues from biota microplastic analysis, testing whether H2O2 can reduce organic material sufficiently to allow accurate identification and quantification of embedded microplastic particles.
Residues of organic material after chemical digestion are a common issue in the filters used for microplastic evaluation in biota. Microplastics embedded within this organic material pose significant challenges for accurately identifying and quantifying them. This study aimed to evaluate the effectiveness of hydrogen peroxide in reducing the organic material from filters already used to analyze microplastics in tissues. We selected filters with homogeneous dark brown color tissue residue content. These filters were subjected to bifiltered distilled water and three concentrations of hydrogen peroxide (6 Also see: https://micro2024.sciencesconf.org/559717/document

Microplastics on plankton samples: Multiple digestion techniques assessment based on weight, size, and FTIR spectroscopy analyses
This study compared KOH, hydrogen peroxide, and two-step digestion protocols for removing organic matter from plankton samples before microplastic analysis, finding that two-step protocols improved recovery but that all methods caused measurable changes in microplastic weight and size, necessitating protocol standardization.
Rapid and efficient removal of organic matter from sewage sludge for extraction of microplastics
Researchers tested hydrogen peroxide combined with enzymatic treatment as an efficient method for removing organic matter from sewage sludge before microplastic extraction, overcoming the limitations of acid digestion for organic-rich matrices.

The effects of weathering-induced degradation of polymers in the microplastic study involving reduction of organic matter
Researchers found that weathering-induced degradation significantly altered how microplastics respond to common purification treatments — such as hydrogen peroxide and enzymatic digestion — used to remove organic matter in environmental samples, suggesting that pristine reference plastics may underestimate damage to real-world weathered microplastics.
Evaluation of organic matter removal by H2O2 from microplastic surface by nano-physicochemical methods
Researchers evaluated how effectively hydrogen peroxide — commonly used to clean microplastic samples — removes the natural organic coatings that build up on microplastics in the environment, using multiple advanced imaging techniques to track changes at the nanoscale. They found that monitoring changes in material softness and temperature response provided more reliable evidence of coating removal than infrared spectroscopy alone, improving the accuracy of microplastic analysis.
