hIany metal ions form complexes with the diethyldithiocarbamate anion, (CtHs)&CSz-(DDC), and can be extracted into organic solvents. Extraction coefficients for metal ions with DDC under some conditions have been reported by several authors [l--6 J \_ For analytical extractions, some complexes, Me(D

Gold and mercury in sea water can be selectively extracted by bismuth diethyldithiocarbamate into chloroform at pH <l. The matrix species and many other trace elements in the system are effectively removed durmg extraction. When neutron activationy-spectrometry is used, the detection limits for gol

Collagen in tissue or tissue ext'racts is usually determined by assaying hydroxyproline, an amino acid unique to collagen. Fitch et nl., in 1955 (l), described a method for measuring the amount of hydroxyproline in acid hydrolyzates of hot trichloroacetic acid (TCA) ext.racts of tissues. They found
