Abstract: The halide can be oxidized with a suitable oxidizing agent to produce halogen gas that can be absorbed by CD-4 to form a colored compound. The absorbance of the compound can be measured at 510 nm and therefore the halide can be determined. The method has been used to determine trace chloride in tap water.

Key words: halide, spectrophotometry, CD-4WT
