INTRODUCTION. Halogen atoms (chlorine (Cl) and bromine (Br)) can strongly influence the atmospheric chemical composition. High levels of halogens have been shown to deplete ozone (O 3) in the stratosphere [] and destroy groundlevel ozone of the Arctic [].There is an emerging recognition that in the troposphere, they can kick start hydrocarbon oxidation that makes ozone, modify the oxidative

May 29, 2003· The role of bromine compounds in the midlatitude troposphere is a yet unresolved issue. From the comparison of satellite measurements with groundbased and balloon measurements [van Roozendael et al., 2] a tropospheric BrO background column of 1 to 3 · 10 13 molec/cm 2 is assumed. But still, direct measurements of BrO in the midlatitude

Relative measurement errors of just 3.4% and 0.84% were indicated for arecoline hydrobromide and tetrabutylammonium bromide, respectively, when comparing WDXRF results to the theoretical Br content of the two materials. Replicate analyses of the former sample indicate bromine measurements can be made with high precision as evidenced by a 0.85% RSD.

Bromine can be estimated by direct measurement of its absorption at 405 nm after extraction with organic solvents, or a reaction with a dye like rosaniline or phenol red is followed. Such colorimetric methods require proteinfree solutions which can be obtained by precipitation of the protein or by alkaline incineration of the organic matter, a procedure which comprises the sum of bromide and organic bound bromine .

The HI716 Checker ® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure bromine. Introduced as an alternative to chlorine, the use of bromine as a sanitizer is increasing in use in many countries. Bromine is less volatile and has more effective results above a pH of 7.4, but is an overall slower acting disinfectant.
