| Abstract: | Stable reagents for the spectrophotometric mercury-iron-thiocyanate method for the determination of halide have been developed. The molar absorptivity for concentrations up to 170 μmole/liter of halide is for chloride 3.4 × 103, for bromide 3.9 × 103, and for iodide 4.0 × 103. Above this concentration there is a slight decrease of the absorptivity for chloride and a slight increase for bromide and iodide. |
