The increasing frequency with which riboflavin deficiency is being discovered in man has given an impetus to the study of this substance in biological fluids wi’ith a view to providing a quick and accurate diagnost,ic method. For this purpose chemical methods of determination are distinctly to be preferred to the more laborious and time-consuming biological and microbiological methods. Several ...
The measurement of combined copper has been used in a number of procedures for the quantitative determination of amino acids and peptides. Pope and Stevens (1) as well as Schroeder, Kay, and Mills (2) determined the combined copper iodometrically. Martin and Mittelmann (3) analyzed for copper with the polarograph. Woiwod (4) used the spectrophotometer to measure the color produced by the reacti...
on the polarograph, isotopes, sulfa drugs, metabolic antagonists and antibiotics, Warburg tissue slice technique, theory and practice of photometric analysis, and electrophoretic fractionation of the plasma proteins. This book will continue to serve a valuable function as a reference text and guide to laboratory techniques and quantitative analytical methods, since in it may be found a descript...

Apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. Infants and young children are very susceptible to amount of trace elements. Copper and zinc are two elements that add in infant food. Lead and cadmium are heavy metals that enter to food chain unavoidably. DPASV is a benefit and applicable method for measurement of trace elements in food produc...
Uranium(VI) is adsorbed as a uranium trifluoroethylxanthate (TFEX)-cetyltrimethylammonium (CTMA) ion-pair complex on microcrystalline naphthalene quantitatively in the pH range 4.2 - 7.0. Without cetyltrimethylammonium as the counter ion, the adsorption is hardly 70%. The metal has been desorbed with HCI and determined with a differential pulse polarograph. Uranium can alternatively be quantita...
