Abstract
Abstract 2-Amino-4-chlorobenzenethiol hydrochloride forms a green precipitate with molybdenum VI at pH 2. The precipitate can be extracted into chloroform and has an absorbance maximum at 720 mμ. The sensitivity of the reaction is 0.0054 μg of molybdenum per cm 2 for log I 0 /I = 0·001. Development of the spectrophotornetric method for the determination of molybdenum included a study of the effect of pH, reagent concentration, rate of complex formation and extraction, temperature and conformity to Beer's law. The method has been applied to the determination of molybdenum in steel and cast iron.
