Photography. Processing wastes. Determination of boron Ingestion-build-48068 Where areas of different construction1 Scope This International Standard specifies 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, which is a stronger acid than the boric acid from which it is formed. It is suitable for boron concentrations of 0,1 mg l and higher. In the range 0,1 mg l to 5 mg l, phosphate is removed by precipitation by lead acetate. In the range 1
