“…A comparison of combustion and wet decomposition techniques showed no significant difference in the titrimetric determination of sulfur (454)• Vanadium pentoxide was employed as an accelerator flux to improve the recovery of sulfur in the analysis of iron and steel (77,181). Thermometric titration determination of sulfur with ±0.001% to 0.004% S accuracy, based on primary and secondary reactions, was employed for steel and pig irons (444) Electron microprobe techniques were used to study sulfur segregation in cast iron (312) and neutron activation analysis was employed in the determination of >2.5 ppm of S in alloy steels (375).…”
