英文名称：Photography — Photographic-grade chemicals — Test methods — Part 5: Determination of heavy metals and iron content

发布日期：1992-12

标准范围

该方法基于试样和重金属标准溶液的制备、预处理、添加硫化钠溶液（用于测定重金属）或1,10-菲罗啉试剂（用于测定铁）、用水稀释、充分混合、转移到两个纳氏比色瓶中，并比较两种溶液的颜色。

The method is based on preparation of test samples and heavy metals standard solutions, preconditioning them, addition of sodium sulfide solution (for determination of heavy metals) or 1,10-phenanthroline reagent (for determination of iron), dilution with water, mixing well, transfer to two Nessler colour-comparison cylinders, and comparing the colour of both solutions.
