A MICRO METHOD FOR THE DETERMINATION OF GASEOUS FLUORIDE

摘要

A METHOD HAS BEEN DEVELOPED FOR THE QUANTITATIVE DETERMINATION OF POTENTIALLY IONIZABLE FLUORINE IN GASES. FROM 1 TO 500 P.P.M. BY VOLUME OF FLUORINE, OR EQUIVALENT QUANTITIES OF OTHER GASEOUS FLUORIDES CAN BE DETERMINED WITH AN ACCURACY OF ABOUT 10%. THE DETERMINATION IS UNIQUE IN THAT PRODUCTION OF COLOR IS USED INSTEAD OF A BLEACHING EFFECT OR A CHANGE OF COLOR.
