โœฆ Synopsis

The electrolysis of simulated ร‘ue gas solution based on sulphite/ sulphuric acid is reported. Two undivided cells were employed, a small batch cell and a sieve plate electrochemical reactor (SPER). With the batch cell, two anode materials were tested for the oxidation of sulphite to sulphate, platinum and graphite. Ebonex and zirconium cathodes were used in connection with both the anodes. High current efficiencies, above 85%, were obtained in all cases, without the formation of elemental sulphur. Comparable results, 85รˆ95%, were obtained with the sieve plate electrochemical reactor, for a current density range of 10รˆ 25 mA cm~2 at low sulphite concentration (0ร‰005 M) in 2รˆ6 M sulphuric acid.

The material balance of nitrogen and sulfur components in simulated flue gas (NO-SO,-H,O-Or-NH,-N,) treated by an electron beam was measured using "N labeled NO (250 ppm). Combinations of chemical analysis, instrumental analysis and mass analysis were used to identify and quantify the nitrogen-cont
