| Zusammenfassung |
| Although reactive halogen species (X*=X•, •X2-, X2
and HOX, where X=Br, Cl, or I) are
important environmental oxidants, relatively little is known about their
kinetics in condensed phases such as seawater and sea-salt particles. Here
we describe a new technique to determine reactive chlorine and bromine
species in aqueous solutions by using allyl alcohol (CH2=CHCH2OH)
as a chemical probe. This probe is combined with competition kinetics in
order to determine steady state concentrations of X*(aq). In some cases the
technique also can be used to determine the rates of formation and lifetimes
of X* in aqueous solution. In a companion paper we reported the results of
our method development for aqueous solutions containing only bromide
(Br-). In this paper, we discuss method development for solutions
containing chloride (Cl-) alone, and for solutions containing
both bromide and chloride. |
