Plasma-liquid system for degradation of pharmaceutical effluent

A novel solution cathode glow discharge geometry for improved coupling to optical emission spectrometry

“…The SCGD has been used to quantitate elemental composition at trace and ultra-trace levels in a wide variety of sample types including silica colloids, 9 nanoparticles, 10 bottled water, 11 wastewaters, 12 honey, 13 and wine. 14 It has also found use with hydride generation, 15 water remediation, 16,17 and nanoparticle synthesis. 18 Because the SCGD-AES is a relatively nascent technique, a variety of methods and geometries have been reported to improve the analytical gures of merit of the technique.…”
