In. Stankov et al., GAS-CHROMATOGRAPHIC DETERMINATION OF TRACES OF MIXED PHOSPHORIC-ACID HALIDES IN AIR, Journal of analytical chemistry, 52(6), 1997, pp. 580-583
A method for simultaneous determination of mixed phosphoric acid halid
es in the air of working premises at the level of the maximum permissi
ble concentration is proposed. The method is based on their different
abilities to substitute alcoxyl radicals for halogen atoms.
