Conclusions
The proposed extraction-photometric procedure for determining elemental sulfur content using dodecanes as the extractant and with purification of the extracts from surface-active substances with aluminum oxide can be used to determine elemental sulfur content in precipitation baths of viscose manufacture within the range from 10 to 60 mg/dm3 or higher, and also for the analysis of precipitation bath sludges.
Scientific and technical documentation has been made up for metrological certification of the procedure.
