BSI BS ISO 7760:2001

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 ÎĽg/l to 4 000 ÎĽg/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.
