โœฆ Synopsis

Two simple spectrophotometric procedures for the quantitative estimation of hypochlorite in commercially available sodium hypochlorite solutions are presented. One method is based directly on the absorbance of hypochlorite in alkaline aqueous media. The other method takes advantage of the quantitative reaction of hypochlorite and ammonia in alkaline solution to form chloramine, which has a higher molar absorptivity. Results of the spectrophotometric assays are compared with results obtained by the titrimetric procedure of NF XII.

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 cal
