A kinetic method for the determination of sulphide and sulphur in steel with Brilliant Cresyl
Blue (BCB) in the presence of Se (IV) is described. The reaction has been monitored
spectrophotometrically by measuring the decrease in absorbance of BCB after 2 min from
initiation of the reaction at 30 degrees C. The method enables rapid analysis of sulphide
over the concentration range of 0.30-10.0 mu g/ml. The limit of detection is 0.2 mu g/ml of
sulphide. Ten replicate analyses of a sample containing 0.30 and 0.60 mu g/ml of ...
