13. Determinação catalitica de molibdenio em plantas, usando analise em fluxo continuo monossegmentado com detecção espectrofotometrica
A procedure has been developed for the spectrophotometric determination of molybdenum in plants using the Continuous Monosegmented Flow Analysis technique with catalytic oxidation of I by H2O2 in acid medium. The analytical signal, the difference between the absorbance resulting from the Mo(VI) catalyzed reaction and the non-catalyzed reaction, was optimized

14. Extração liquido-liquido por fase unica : estudo da separação de molibdenio com tiocianato e agua-etanol-alcool amilico
In this work, modified molybdenum analysis methods were studied with the purpose of improving the reproductiveness of the method using tiocyanate. It was found that the use of tin chloride and hydroxilamine as reductors improve reproductiveness, the same impronement being achieved with a mixture of amylic alcohol-benzene extraction solvents. The separation o
