Sôbre uma modificação na determinação do Molibdênio em Plantas

Abstract

The author proposed a new modification on the thiocyanate-stannous chloride method for the determination of molibdenum, when is used a heavier-than-water solvent for extrating the colored molybdenum thiocyanate complex. Carbon tetrachloride - butyl alcohol is the mixture proposed, and the results obtained give a good precision and more sensibility than the other method that use carbon tetrachloride-isoamyl alcohol as extractant.
