Photography — Processing wastes — Determination of boron 摄影与摄影;处理废物——硼的测定
发布日期: 1996-11-07
给出了两种测定摄影加工废弃物中硼的方法。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及更高浓度的硼。第二种替代方法是使用亚甲基蓝的分光光度法,其浓度范围为0.1 mg/l至1.0 mg/l。
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.
