J.Am. Chem. Soc.(JACS) точно online, с остальными надо топикстартеру разобраться.
starless, помочь иногда не грешно, не все же видят проблему насквозь

Я готов помочь, но не готов лезть в веб оф саенс ради джакса. Если все остальные журналы такие же -- какой в этом смысл?

Эти автор поста может и сам посмотреть. Большинство из остальных тоже есть в электронном виде, но не за эти годы. По крайней мере я их не нашел.
Поиграл с Reaxys и убедился, что по автору там искать весьма непросто

The use of complexons in chemical analysis. IX. The colorimetric determination of copper by sodium diethyldithiocarbamate
By Sedivec, V.; Vasak, V.
From Collection of Czechoslovak Chemical Communications (1950), 15, 260-6. Language: English

cf. preceding abstr. The specificity of reaction of Na diethyldithiocarbamate (I) with Cu can be increased by adding to the ammoniacal soln. ethylenediaminetetraacetic acid (II), which forms sol. complexes with Fe, Ni, Co, Mn, etc. Under these conditions only the I complexes of Hg, Pb, Cd, Ag, and Bi are pptd.; the first 3 are white and form colorless solns. in org. solvents; Ag and Bi complexes give yellowish solns. in org. solvents. To det. traces of Cu in Ni, Co, Fe, and Mn salts, add an excess of II to the soln., make alk. with NH3, and add a soln. of I. Ext. the resulting soln. twice with EtOAc. Clarify the cloudy ext. by adding a small amt. of EtOH. Measure the photometric absorption with use of a green filter. For Cu in steel, dissolve 1 g. in HNO3, filter off any silicic acid, and dil. the filtrate to 250 to 1000 ml.; to a 50-ml. aliquot add 0.5 to 1.5 g. of II, make alk., add I, ext., and measure as described.

Sodium diethyldithiocarbamate as a reagent in volumetric analysis
By Sedivec, V.; Vasak, V.
From Collection of Czechoslovak Chemical Communications (1950), 15, 52-64. Language: English

A Ag electrode (I) is useful for potentiometric measurements with (C2H5)2NCSSNa(II). Solns. of Ag, Cu, Pb, Cd, Ni, and Zn can be detd. at 0.01 N concn. in neutral soln. by potentiometric titration with 0.1 M II by using I and a satd. calomel electrode. With Fe and Co the end point and the equivalence point do not agree. The salt of Hg is too insol. and the salts of Mn, Tl, Al, Cr, Mg, Ba, and Ca are too sol. for the method. Two or more cations can be titrated successively if 10-15% EtOH and KNO3 are present and an equal vol. of peroxide-free Et2O is stirred with the soln. to ext. the first ppt. as it is formed. II is insol. in ether.

Carbamates, monothiocarbamates, and dithiocarbamates. VIII. Polarographic studies of the kinetics and decomposition mechanism of dithiocarbamic acids in acidic medium
By Zahradnik, R.; Zuman, P.
From Collection of Czechoslovak Chemical Communications (1959), 24, 1132-45.

Carbamates, monothiocarbamates, and dithiocarbamates. VIII. The kinetics and mechanism of decomposition of dithiocarbamic acids in acid medium, studied polarographically
By Zahradnik, R.; Zuman, P.
From Chemicke Listy pro Vedu a Prumysl (1958), 51, 231-42.

cf. C.A. 51, 13755i. The kinetics of the decompn. of 9 monoalkyl- and 9 dialkyldithiocarbamic acids were studied as a function of pH. The decompn. of dithiocarbamic acids yields an amine and CS2. The rate-controlling reaction is the decompn. of the dipolar ion RR'HN+CS2-, the concn. of which depends on the preceding dissocn. equil. Steric influences and the effect of the electron-d. changes caused by the substituents on the N atom are discussed.
