A new method for the determination of inorganic salts of chloride and bromide is described. The method is based on the facts that iodine forms complexes with the anions and that these complexes absorb strongly in the UV region. The molar absorptivities of I2Br- at 265 nm and I2Cl- at 245 nm were calculated to be 3.27 X 10(4) and 2.3 X 10(4) M-1 cm-1, respectively.
