【Abstract】 The determination result of fluoride in air emission from fixed sources has a significant relation with whether the sampling system is heated or not, sampled air flux and the accuracy of sample PH adjustment. Comparative experiment shows that, monitoring result will be lower if the air flux is high and not heating the system, and result will be higher if PH is not properly adjusted.更多还原
