Proper conditioning of the hollow cathode by sputtering is critical to the analytical performance of the hollow cathode. A pulsed discharge procedure was developed to condition the 1.5- × 5-mm stainless steel cathode. A scanning electron microscope was used to study the surface structure resulting from the conditioning. The resulting hollow bottom was bulb-shaped and the surface was mirror-like, very smooth, and shiny. The emission intensities from smooth cathodes were greater that those from the rough ones. The precision obtained here was 3–5% for Na, 5–8% for Li, and 4–10% for K. Three working curves for each element were made on different days with different cathodes that had been conditioned in the same manner for 4 h by sputtering. The three working curves virtually coincided when plotted in the same figure, demonstrating the precision and reproducibility from day to day of the hollow cathode discharge method as developed in this laboratory. The 3-σ detection limits calculated from slopes of working curves are 0.32 pg, 0.35 pg, and 3.2 pg for Na, Li, and K, respectively.

Hexachlorobenzene (HCB) is a persistent organic pollutant and poses great threat on ecosystem and human health. In order to investigate the degradation law of HCB, a RuO2/Ti material was used as the anode, meanwhile, zinc, stainless steel, graphite, and RuO2/Ti were used as the cathode, respectively. The gas chromatography (GC) was used to analyze the electrochemical products of HCB on different cathodes. The results showed that the cathode materials significantly affected the dechlorination efficiency of HCB, and the degradation of HCB was reductive dechlorination which occurred only on the cathode. During the reductive process, chlorine atoms were replaced one by one on various intermediates such as pentachlorobenzene, tetrachlorobenzene, and trichlorobenzene occurred; the trichlorobenzene was obtained when zinc was used as cathode. The rapid dechlorination of HCB suggested that the electrochemical method using zinc or stainless steel as cathode could be used for remediation of polychlorinated aromatic compounds in the environment. The dechlorination approach of HCB by stainless steel cathode could be proposed.
