A simple, rapid and accurate method for the spectrophotomteric determination of sulphide in non-polar media is described. The method is based upon the reaction of mercury(II) thiocyanate with sulphide to release thiocyanate which .reacts with iron (III) to form iron­thiocyanate. The reaction is performed in non-aqueous medium. Cyclohexane and iso- octane are used as organic solvents separately. The effects of a number of parameters like time, tempera­ture, concentration of reagents and diverse ions are investigated. The method has significant potential of determining sulphur in sulphur containing organic compounds.
