Thallium dithizonate

Attempts to establish a useful dithizone method in the determination of thallous ion have been carried on at Union College by Snyder (19). Because the previous work had not produced satisfactory results and because in general thallous dithizonates have not been studied, the following work, under Dr. W. G Ewing’s guidance, was undertaken

Determination of metal cyanide and thiocyanate complexes by kjeldahl-gunning and carius sealed tube digestion methods

Small amounts of metal cyanide and thiocyanate complexes can be determined using either the Kjeldahl-Gunning or Carius sealed tube digestion method. The results obtained by the Kjeldahl-Gunning method are somewhat low and the values are scattered. The Carius scaled tube digestion enables analysis not only of metal cyanide and thiocyanate but also of mixed phenanthrolinecyanide complexes. The results are reproducible and more accurate than in. the Kjeldahl-Gunning method.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/32431/1/0000512.pd

Determination of semimicro amounts of tellurium by electrodeposition

Electrodeposition of tellurium in micro or semimicro amounts can be achieved using copper or copper-plated platinum cathodes. Best results are obtained from electrolytic baths of approximately 2 M sulfuric acid, 0.4 M ammonium sulfate, 0.1 M sodium tartrate and 0.06 M sodium nitrate. Electrodeposition of tellurium can be carried out with an accuracy better than 1% at the 90% confidence level.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/32271/1/0000333.pd

IUPAC-NIST Solubility Data Series. 80. Gaseous Fluorides of Boron, Nitrogen, Sulfur, Carbon, and Silicon and Solid Xenon Fluorides in all Solvents

The literature has been searched through 2002 June for solubility data on the gases BF3, NF3, N2F4, SF6, CF4, CHF3, CH2F2, CH3F, C2F6, CHF5, 1,1,1,2-C2H2F4, 1,1,1-C2H3F3, 1,1-C2H4F2, CH5F, C3F8, c-C4F8, C2F4, 1,1-C2H2F2, C2H3F, C3F6, C3F6O, and SiF4 and the solids XeF6, XeF4, and XeF2 in all solvents. The data are compiled here. Where feasible evaluations have been carried out. The evaluations were mostly carried out for water as a solvent as the water systems are the most extensively studied. For other systems there is often only one set of measurement or two sets of measurements, which do not agree well. Evaluation of such systems will have to wait on more experimental measurements
