INVESTIGATION OF THE FUNCTIONALITY OF DIFFERENT BURNER TYPES USED FORTHE WICKBOLD DECOMPOSITION METHOD

The functionality of different burner types used for the Wickbold deco mposition method was investigated to understand the low recovery rate problem. The elements chlorine and sulphur were the subject of recover y experiments. The influence of the amount of sample transported into the oxyhydrogen flame on the efficiency of combustion is presented. Th e difference between the manner of transportation into the flame, dire ct nebulisation of liquids or previous evaporation are investigated. A new nebuliser for introducing liquids into the oxyhydrogen flame with an evaporation step was developed to reduce decomposition problems.
