Scope
HG/T 2416-2007 is the English-translated version of 照相化学品 成色剂微量硫的测定 分子吸收分光光度法.
HG/T 2416-2007 belongs to the photographic chemicals group of the Chinese chemical industry standards and describes a molecular absorption spectrophotometric method for trace sulfur in colour couplers. The method is written for couplers whose sulfur can be reduced with potassium borohydride, and the standard states the detection range over which the determination holds. Being a recommended standard, it is applied by agreement rather than by obligation. GB/T 602, GB/T 603, GB/T 6682 and GB/T 9721 are quoted, covering the preparation of reagent solutions, water for laboratory use and the spectrophotometric technique itself. The edition replaces HG/T 2416-1993. Issued on 13 April 2007, it has applied since 1 October 2007.
