Abstract
Granatelli's method for the determination of sulphur in liquid hydrocarbons has been modified to permit the determination of total sulphur in purified light petroleum distillate at concentrations below 4·0 p.p.m. w/v. A mixture of propan-2-ol and water is used as the reaction solvent in a rapid method for the determination of total sulphur in light petroleum distillate in the range 0·1 to 4·0 p.p.m. w/v with a precision of ±9 per cent. of the determined value. For concentrations in the range 0·01 to 0·10 p.p.m. a more lengthy method is given, which has an absolute precision of ±0·01 p.p.m. w/v.Keywords
