Photography — Processing waste — Determination of hydroquinone

OVERVIEW

This International Standard specifies a spectrophotometric method for the determination of hydroquinone in

photographic processing waste.

This method can be applied to samples containing hydroquinone in the concentration range of 200 µg/l to

4 000 µg/l; aminophenols and phenylenediamines should also be determined by this method. However, sulfonated

hydroquinones or products from the further oxidation of benzoquinone will not be determined.
