Chemiluminescent detection of reduced sulfur compounds with ozone
A method is described for the chemiluminescent detection of H/sub 2/S, dimethyl sulfide (DMS), and other reduced sulfur compounds at the sub-ppB levels by their oxidation with ozone. At sulfur concentrations of < 100ppB, the emission intensity was found to be first order with respect to sulfide, and the calibration plots were linear. At higher concentrations (500ppB) of H/sub 2/S, a reaction order of 0.5 was noted. Detection limits for H/sub 2/S, DMS, CH/sub 3/SH, and thiophene of about 4, 0.3, 0.1, and 12 ppB, respectively were determined. The interference of various substances (e.g. hydrocarbons, NO, NO/sub 2/, acetaldehyde, and SO/sub 2/) on the determination of reduced sulfur compounds is reported.
