Heterogeneous Aggregation of Microplastics and Mineral Particles in Aquatic Environments: Effects of Surface Functional Groups, pH, and Electrolytes

Antibiotic-mediated heteroaggregation and sedimentation of nanoplastics with minerals: Mechanisms and environmental implications in natural water

Determining the Impact of Surfactant Type, Concentration, and Solubility on Microplastic Aggregation

AI summary · Read the abstract

Undergraduate researchers tested the surfactant Tween 80 and Span 80 at varying concentrations to aggregate and recover microplastics from water samples, exploring how surfactant type and preparation methodology affect recovery efficiency. This novel aggregation methodology could improve detection and quantification of microplastics in water, which is critical for understanding exposure levels in drinking water and aquatic ecosystems.

Aggregation and Aggregate Strength of Microscale Plastic Particles in the Presence of Natural Organic Matter: Effects of Ionic Valence

AI summary · Read the abstract

Calcium ions promote stronger aggregation of polyethylene microplastic particles in the presence of natural organic matter through divalent bridging, producing more cohesive aggregates than monovalent potassium ions. Understanding how microplastics aggregate under different water chemistry conditions is important for predicting their transport, sedimentation, and bioavailability in natural aquatic environments.

Alkoxy-silyl Induced Agglomeration: A New Approach for the Sustainable Removal of Microplastic from Aquatic Systems

AI summary · Read the abstract

A sol-gel agglomeration technique using alkoxy-silyl compounds clusters microplastic particles of any type, size, or density into larger aggregates that float to the water surface and can be removed with standard sand traps, offering a wastewater treatment approach that works independently of particle characteristics. This technology addresses a critical gap, as conventional wastewater treatment plants fail to capture the smallest microplastic particles that pass through into waterways.
