In situ Detection of Microplastics: Single Microparticle‐electrode Impacts

Electroanalysis 2017 39 citations

AI summary Read the abstract

This study developed an electrochemical method using particle-impact techniques to detect and size individual polyethylene microparticles in water solution. The novel analytical approach enables detection of microplastics in aqueous samples in situ, without the need for filtration or sample processing that could introduce contamination.

Abstract Particle‐impact electrochemistry is employed to study spherical polyethylene microparticles suspended in an aqueous solution. This electrochemical method detects polyethylene microparticles impacting on a carbon fiber electrode generating a transient current response or “spike”. We interpret the physio‐chemical origin of the spikes and accurately identify particle size distributions and concentrations for microparticles of sizes 1–10 μm.

Microplastics detection by impact electrochemistry

AI summary Read the abstract

This paper explores impact electrochemistry—a technique where individual particles colliding with an electrode generate detectable electrical pulses—as a method for detecting and characterizing microplastics in water. The approach offers the potential for rapid, single-particle detection without the need for complex sample preparation or optical instruments, which could make microplastic monitoring cheaper and more accessible. Developing faster and simpler detection methods is important for scaling up environmental monitoring programs.
