An extremely sensitive photometric procedure using aqueous solutions of sulphochrome and cetyl pyridine chloride has been developed for determining microquantities of iron in high-purity quartz, silica, sand and crystal glass. A determination can be completed in 2 hours, including time for decomposing the samples.
