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.
