In Situ EPR Spin Trapping and Competition Kinetics Demonstrate Temperature-Dependent Mechanisms of Synergistic Radical Production by Ultrasonically Activated Persulfate

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 56(6), P. 3729 - 3738

Published: Feb. 28, 2022

Ultrasound coupled with activated persulfate can synergistically degrade aqueous organic contaminants. Here, in situ electron paramagnetic resonance spin trapping was used to compare radicals produced by ultrasonically (US-PS) and its individual technologies, ultrasound alone (US) heat-activated (PS), respect temperature. Radicals were trapped using 5,5-dimethyl-1-pyrroline-N-oxide, DMPO, form detectable nitroxide adducts. Using initial rates of radical adduct formation, compared US PS, US-PS at 40 50 °C resulted the largest synergistic production radicals. generated from reasonably consistent 70 °C, indicating that temperature had little effect on cavitational bubble collapse over this range. However, synergy indexes calculated showed ultrasonic activation interface changes From these results, we speculate higher temperatures enhance uptake into cavitation bubbles via nanodroplet injection. DMPO-OH predominant detected for all conditions. competition modeling presence nitrobenzene atrazine probes SO4•- predominated. Therefore, signal is derived subsequent DMPO-SO4- hydrolysis DMPO-OH. Spin effective quantifying total formation but limited measuring primary speciation case.
