标准摘要
[中文适用范围]： 本标准规定了测定照相冲洗废物中对苯二酚的分光光度法。 本方法适用于对苯二酚浓度为200 μg/l～4 000 μg/l的样品；氨基酚和苯二胺也应采用该方法测定。 然而，磺化氢醌或苯醌进一步氧化的产物将不会被测定。 [外文原描述]： 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.
