## Abstract The limitations of existing methods of testing for sulphur dioxido and sulphur trioxido are discussed, and a now method proposed whereby these constituents are absorbed under acid conditions. By absorption of sulphur trioxido in distilled water, absorption and subsequent oxidation of th

## of The absorption in the range X = 262 nm (in cyclohexane) of elemental sulphur (S,/) , added to bitumen extracted from the Athabasca tar sands, at concentrations ranging from 0.2 to 4-O%, was used to determine its concentration with a reasonable accuracy. The selective concentration of S,, in
