Photometric Determination of Trace Tin with Sodium Dodecyl Sulfate(cas 151-21-3) - Salicylfluorone

A high selectivity and high sensitivity spectrophotometric method for the determination of trace tin was proposed. The results show that the anionic surface active sodium dodecyl sulfate(cas 151-21-3) has a special selectivity. In the presence of dodecyl sulfuric acid, tin and salicyl Fluorone in the formation of highly sensitive ternary complexes in strong acidic media, the common interference ions do not occur similar to the color reaction, with a high selectivity, without separation can be directly measured in the steel samples of trace tin.
