标准范围

本国际标准规定了氨和其他挥发性胺的测定方法，这些胺可以通过强碱从摄影处理废物中释放出来，结果用氮表示。本方法适用于工业中典型光处理废弃物中氨浓度的测定氨的浓度范围为10 mg/l至200 mg/l，氮的浓度范围为8 mg/l至160 mg/l。测定了其他挥发性胺但它们在光处理废物中的浓度通常很低。

This International Standard specifies a method for the determination of ammonia and other volatile amines that canbe 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 inthe 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 determinedas ammonia, but their concentrations in photoprocessing wastes are usually very low.
