Abstract |
The original project was to evaluate the Arthur D. Little Method by comparison with the Inter-Society Committee Method for steam distillation from perchloric acid, using field and laboratory samples. Subsequently, the work was reoriented towards primary evaluation of the Decker method and, later, the EPA method 13 (similar to Decker). The fluoride measurement methods are described and the results compared. The parameters of the fluoride determination method are as follows: distillation type, acid, temperature and measurement mode (SPADNS or electrode). Three sampling trains were tested, evaluated and illustrated. The basic design considerations to develop a continuous fluoride source monitor are presented. (Modified author abstract) |
