Abstract
An unsuccessful attempt to develop an air sampling and analytical method for the determination of vinylidene-fluoride (75387) and vinyl-fluoride (75025) in environmental work air was described. The selection of the gas chromatographic (GC) operating conditions and standards was discussed. GC determination of the derivatives of the above compounds with bromine was explained. Nonreactive and reactive sorbents, capacity screening tests, desorption efficiency, and stability tests were evaluated. Carbonaceous sorbents were tried. A bromine impregnated petroleum charcoal sorbent exhibited excellent capacities for both compounds with 1,2-dibromo-1,1-difluoroethane (75821) and 1,2-dibromofluoroethane as reaction products. Recovery was only 50 to 66 percent. The authors suggest future work is needed for maximizing and standardizing the yields of the reaction products of bromine with the analytes.
