Cold Atmospheric Plasma Induced Degradation of Organophosphate Pesticides on Kevlar Swatches

ABSTRACT Cold atmospheric plasma (CAP) was evaluated for degrading organophosphate pesticide (OP) residues (acephate, malathion, and dimethoate) from Kevlar fabrics. Fourier transform‐Infrared (FTIR) spectroscopy, Scanning electron microscope (SEM) imaging and tensile strength testing confirmed that CAP treatment preserved Kevlar's structural integrity and mechanical properties. Results show degradation efficiency increased with higher power, shorter discharge gaps, and longer exposure duration. Hyperspectral imaging supported the detection of plasma‐induced spectral changes, reinforcing the presence of reactive species. The strong oxidative potential of CAP facilitated the rapid breakdown of OPs into nontoxic byproducts. These findings demonstrate the potential of CAP as a portable, energy‐efficient solution for dry surface decontamination, particularly in environments where conventional chemical or water‐based methods may be unavailable.
