Scope

Gives two methods for the determination of boron in photographic processing wastes. The first method is the estimation of borates by titration of the boric acid-mannitol complex. Suitable for boron concentrations of 0,1 mg/l and higher. The second alternative method is a spectrophotometric technique using methylene blue which can be used in the concentration range of 0,1 mg/l to 1,0 mg/l.
