Photography. Processing waste. Determination of hydroquinone Ingestion-build-239834 highly efficient rod ends1 Scope 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 g l to 4 000 g 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.
