标准摘要
[中文适用范围]： 给出了两种测定照相冲洗废物中硼的方法。 第一种方法是通过滴定硼酸-甘露醇络合物来估计硼酸盐。 适用于 0.1 mg/l 及更高的硼浓度。 第二种替代方法是使用亚甲蓝的分光光度技术，其使用浓度范围为 0.1 mg/l 至 1.0 mg/l。 [外文原描述]： Gives two methods for the determination of boron in photographic processing wastes. The first method is the estimation of borates by titration of the boric acid-mannitol complex. Suitable for boron concentrations of 0,1 mg/l and higher. The second alternative method is a spectrophotometric technique using methylene blue which can be used in the concentration range of 0,1 mg/l to 1,0 mg/l.
