标准范围

本国际标准规定了分光光度法测定水中对苯二酚的方法摄影加工废物。该方法适用于浓度范围为200μg/l至200μg/l的对苯二酚样品4000μg/l；氨基酚和苯二胺也应通过该方法测定。然而，磺化对苯二酚或苯醌进一步氧化的产物将不予测定。

This International Standard specifies a spectrophotometric method for the determination of hydroquinone inphotographic processing waste.This method can be applied to samples containing hydroquinone in the concentration range of 200 μg/l to4 000 μg/l; aminophenols and phenylenediamines should also be determined by this method. However, sulfonatedhydroquinones or products from the further oxidation of benzoquinone will not be determined.
