A selective electrode was manufactured to determine the sulfur ions by sedimentation method in industrial waters in oil refineries of North Refineries Company, Baiji, Iraq. The linear response on a wide range of concentration (from 1.0·10–1 to 1.0·10–6M) Na2S with a Nernst response of 28.229 mv per decade, theoretical value for slope of 29.58 mv per decade, correlation factor of 0.9998, detection limit of 2.287·10–7 at 25–35°C, pH 6.0–12.0, and the best concentration of the filling solution of 10–6M with a fast response time (5–13 s). The direct method were %RSD for 0.5772– –0.7430, %RE for –0.1, 3.7 and %REC for 99.9, 103.7.
Some unpublished information about history of Polish oil industry has been presented. The special attention was given to the personality of Ignacy Lukasiewicz. Information comes directly from Wachal family, which a member, Wladyslaw Wachal (senior) worked together with Ignacy Lukasiewicz the father of Polish oil industry.
