标准摘要
[中文适用范围]： 本标准规定了照相冲洗加工废物中强碱释放出的氨和其他挥发性胺的测定方法，结果以氮表示。 该方法适用于测定10 mg/l至200 mg/l氨或8 mg/l至160 mg/l氮范围内的典型光冲废物的氨浓度。 其他挥发性胺被确定为氨，但它们在照相冲印废物中的浓度通常非常低。 [外文原描述]： This International Standard specifies a method for the determination of ammonia and other volatile amines that can be liberated from photographic processing wastes by strong alkali, the results being expressed in terms of nitrogen. The method is applicable for the determination of the ammonia concentration of typical photoprocessing wastes in the range of 10 mg/l to 200 mg/l of ammonia or 8 mg/l to 160 mg/l of nitrogen. Other volatile amines are determined as ammonia, but their concentrations in photoprocessing wastes are usually very low.
