A spectrophotometric method was developed for the determination of dimethyl disulfide (DMDS) in complex gas mixtures emitted by the rubber industry. The method allows organic disulfides to be quantitated in amounts exceeding 1.5 mg/m3 gas (expressed as DMDS) and can be applied to the determination of disulfides in air at workplace as well as in gaseous products of thermal and biological decomposition of solid substances. The method enables disulfides and mercaptans to be determined simultaneously.
